Dear Hammond organ fans,

Aging Creates Performance & Sound Degradation

Today, in 2014, things have changed for these vintage instruments. Most of these Hammonds and Leslies are no longer in quite the shape they used to be in their younger days.

Of course, due to aging components, the deterioration and degradation of the sound and performance has become the undesirable vintage Hammond and Leslie reality.

Despite the fact that they were built with extremely high quality standards, many components had a life expectancy of 15 to 20 years . . .

. . . So, that means that even the last Hammond B3 from 1975 now needs maintenance and restoration to get back in shape.

. . .They have become so Dull and Lifeless that it sounds like the Leslie has been wrapped in carpet. . .

In fact, some Hammonds and Leslies just don't scream any more!

Many of them lack punch and brilliance and sound as if they've been muffled...

Others lack a lot of bass, too, not to mention all the audible "HUM" "BUZZ" and "POPS", which should be out of the picture, but somehow they are now associated with these antique instruments.

So what's left to enjoy?

Let's face it... A B-3 could be compared to an old '55 Cadillac! 


Both of them are classics. But to keep them alive they require some maintenance from their owners...

"My B3 Doesn't Scream As Much As It Used To..."

By talking with long-time Hammond and Leslie owners I have discovered that I was not the only one who was deceived by the sound of these instruments.

I was shocked by the comments from veteran owners of these instruments, namely, the people who had acquired their Hammonds back in the early 1970's.

These guys were now criticizing the same tone degradation and overall performance of their instruments through the years.

They were all saying things like: "I don't know what happened to my B3 but now it doesn't scream as much as it used to 20 years ago. Now it is just  flat sounding!"

So I had to find what the critical audio components were, to make sure I replaced them.

When I consider the time and energy that I have committed to discovering what I know today, I realize that it is not only valuable but almost priceless.


Trying to repair restore and improve the sound and performance of your Hammond and Leslie can often be a long and difficult struggle...

(Unless you get help from a winner...)

The time and money I have invested will certainly benefit you by skipping the learning curve to make sure that you don't make the same mistakes that I did and to make sure that you succeed the first time!  

As you already know, we play music to express our emotions and feelings and we use the organ as a tool to communicate those emotions.

When the organ doesn't sing or scream or doesn't have the punch you need,  how can you express yourself?

If you are not sure, just listen to the organ solo in the song "Evil Ways" from Santana. You will know exactly what I refer to. Just hear that FAT, BIG and RICH sound and expressive scream that can only be produced by a Hammond and Leslie in top shape!

However, if you want to be bored, just play an original vintage B3 and Leslie that has not been restored...

They've lost Bass, they are Flat and lack Treble...

They now give off a lean, mid-range sound...

I have played on many B3s that just didn't deliver because of many technical problems. Not only is it boring to play on those instruments, but it can be very frustrating too, especially when you know what you are missing.

In my opinion, the Hammond B-3 and similar organs are probably one of the top keyboards in the world that has that range and potential to express various human emotion intensities.

But sadly, when they sound bad the message won't be transmitted, so they are not much better than any clone out there.

My 16 Years Of Experience Rebuilding Hammonds and Leslies is Yours Risk-Free

If you own an original vintage Hammond and Leslie, I am sure that you can relate to what I said previously. You hear them on the radio, live on stage, or on late night television programs, and the same instrument seems to sound and perform so much better than your equipment.

I have been in that position before and I always wondered why my organ didn't sound as good as the professionally recorded ones , until I discovered this.

My expertise in Hammond and Leslie restoration began in 1994 because of the frustration with the difference in tone from an original 1958 B3 in comparison to the organs I could hear in concerts and on professional recordings.

I started intensive research to find out why that organ would not perform and sound as good as theirs, and how I could bring it back to life. I have discovered that all of these touring Hammond organs and Leslies were restored to factory specifications.

That's why the sound was so good! Because these guys were rebuilding the electronics in the organ and in the Leslies.

Today, there are shops that specialize in the restoration of these vintage instruments, mostly for professional touring organists. After talking with a great number of Hammond specialists I have accumulated enough knowledge and tips to restore these vintage beasts! And you will benefit from that expertise.

After rebuilding that 1958 B3 and that Leslie 122 RV with amazing results, I knew for sure that these "beasts" needed some maintenance because the proof was finally there. The sound was as good if not better than when new!

After my restoration, I had finally duplicated the exact same sound as I could hear on professional recordings. No "HUM" or funny noises, static "BUZZ" or "POPS” . . .

. . . just the clean classic fresh drawbar definition and Leslie tone that we all love!

After that, I started to restore organs for others with the same success.

But Wait...

I don't want you to do the mistakes I made by listening to bad recommendations that cost me so much time and money...

There are tons of guys out there that claim to be experts, but they are only expert at taking money out of your wallet!

I don't want you to spend time and money on components that don't need to be replaced! And you can avoid this when you have the knowledge that I am about to share with you.

The First Category of Technicians: The Parts Seller. . .

These guys don't care about you. They just want to hear the sound of the bell ringing on their cash register.

Let's face it...

Many of them have businesses to run and personnel to pay, so their goal is to sell as much as possible and fast.

In other words, their job is to try to sell you parts that you may not really need. Did you ever take your car into a garage and spend hundreds of dollars to have it repaired, and later realized that the real problem could had been fixed for a few bucks?

Well, It happened to me and I was raging! This manual will help you prevent that from happening to you.

The Second Category of Technicians: "The Lazy Museum
Security Guard"

In my 14 years of experience, I've talked with many Hammond technicians. The second category of technicians are the ones who don't want to work.

Let me explain...

While the first category sells you parts that may or may not make your organ sound better or possibly worse than before, the second one likes to keep the Hammonds in their "Museum state" without any desire to restore the classic sound.

This group of technicians is usually older and soon to be retired. They are purists and traditional, resisting having to restore them back to original.

These technicians will work on this equipment ONLY if they are dead or broken . . . Despite their vast experience in the field, I have always been shocked to realize that after talking with some of them, they were on a totally opposite spectrum than me!


That’s because in most cases they are technicians NOT musicians! Let me explain. Most of them will have the following mindset, and they will say things like: "It plays well, it's in mint condition, it makes a sound and it works. Why bother?"

My favorite answer to them is always the same one...

“I have had an excellent working 1980 Pontiac Trans-Am with a very aggressive looking red eagle on a glossy white paint job, in mint exterior condition.

BUT, the car also had rusted floors and transmission seal leaks, not to mention that I was also buying the Prestone wholesale!”

Pretty on the outside, falling apart mechanically on the inside . . .

Of course the average vintage Hammond B3 organs for sale are no longer truly stock because the aged components are no longer working at their proper specs!

So therefore the factory stock sound and electrical operation has long gone!

In most cases, the technicians won't even realize that these organs are now a pale imitation of what they used to be!

Now, before I alienate all the technician community, I will specify that there ARE a few technicians who care about the sound quality of these instruments.

Who are they?

In most cases, they are also musicians!

I'm living PROOF that you can restore your Hammond and Leslie . . .

. . .  without spending a lot of money!

That's why I have decided to compile a book on how to restore the performance and sound of Hammonds and Leslies. Otherwise, this information may not be available to you because that kind of information is so hard to collect and hard on the wallet.

It took me years to discover and to compile that information and now I share it with you.

The long distance calls that I made to talk to other Hammond technicians across the country, or the travels back and forth to the electronic shop to purchase and try different components, will benefit you.

Sure, it is possible that taking your organ and Leslie in to a technician may solve your problems but, it is NOT a guarantee . . .

. . . because I found many technicians in my venture who just ignored the steps to restore these instruments and never have restored any Hammonds or Leslies correctly before!

So choosing your Hammond specialist is a challenge by itself.

Shipping your equipment to a different state or province is another painful thing to consider, and I am not taking into account the hourly fee that will be charged for the labor!

"Hi Pat,

I just purchased your e-book last night and I am eagerly buzzing around through all your great info. I was wondering if you could tell me more of your background. You seem to know a great deal.

I am a professional bassist (upright and elec.) and have been most of my life. I grew up playing in bands with B3 players from my early days in Rock and Blues bands to later days in Jazz."

Thanks Pat

"Hi Pat! Man that’s a great guide! This is an extremely
valuable and well-done book that should be considered
mandatory reading for anyone even considering ' gettin' under the hood' on a console Hammond, especially the B-3.

The detailed, step-by-step instructions and the clear, illustrative photos offer even a regular guy like me, a player but certainly not a technician, a comprehensive roadmap to many of the most common and beneficial restoration tasks, as well as some great ideas for ' tweaking ' the sound of your Hammond.  

I sure could have used this guide for the full-restore I did on a beat-up ol' 1954 Hammond B-2 over the would have made life a lot easier. Honestly, I think anyone will be glad to have this book in hand !"

Thanks Pat!"

"Since I need to maintain four organs and six Leslies in my rental fleet, this book has come in handy in order to save trips to the Hammond tech. I move organs 6 or 8 times a month, and play in 2 Blues bands and am always having to tune up something at the gig.

I've provided organs to Monterey Jazz Fest and Monterey Blues Fest as well as many others in Central California for 15 years. This book is a lifesaver for me. Thanks again,"

Allan playing his Hammond B-3 organ

- Allan "B3blues" Carroll, CA


"I've been both a fan of the Hammond tonewheel sound and a performer on the B3 since 1967. And through the years I've gained quite a bit of knowledge on how the systems work and ways to enhance the sound.

Currently, I'm an authorized full line dealer for the Hammond Suzuki Organs, Keyboards, and Leslies in Nebraska, Northern Kansas and Colorado here in the United States. I am simply amazed at how the new organs sound and perform.


First though, my allegiance is with the vintage Hammonds and Leslies that started it all. But, as we all know, those systems are aging and keeping them up to spec is the trick.

As I was browsing online recently I happen to come across your website and the e-book offer. It's cost and the content that was included sounded very appealing to me. So, I figured that was definitely worth the investment and ordered the Hammond B3 and Leslie Tips Restoration ebook.


Much of it I was aware of and what I didn't know I found very informative! In fact, a person kind of wonders if he would have ever found some of this info.

I really appreciate your research! It definitely will be helpful. Whenever I can sit down and read information on the Hammond Organ and how to maintain and tweak the sound, it is always a treat!!!.

Many Thanks,


Steve playing his B-3 organ with his band

- Steve Jacobi, NE


"Hi Pat!

Thanks so much for all your hard work making this e-book available to guys like me! My 1963 A-102 started going down hill this year. It’s lost all its punch and high end. I knew it needed some TLC but I didn’t know where to turn.

I phoned a few service companies, but I wasn’t willing to pay the amount of money they were quoting. Then I stumbled across your “Hammond B3/Leslie 122/147 Improvement & Restoration e-Book”. I have no previous electronics experience, although I can manage a soldering gun.

Your info has given me all the information I need to restore my Hammond and Leslie 147 back to it’s original glory! Maybe even better! Best of all I can do it all myself!!!

(And thanks for helping me out with all the extra questions via email!)

All the best!"

I just wanted to express how pleased I am with the results of the info you gave in your ebook that I recently purchased. I have all the necessary work done except for your tube substitution tips for the Leslie.

Everything I changed was an improvement and when I finished it was as great sounding as you described. I have to give you and God all the credit for your book.

This is the sound I have always heard back when I was playing in bands in the 60\'s up until now. I never had a B-3 back then just an L-112 and 147 Leslie.

Thank you so much for all your research. May God bless you and your family to the fullest."

- Charles Pollard,


“Pat I have been looking for a quality Hammond restoration book and finally found it. ‘Hammond B-3 And Leslie 122/147 Improvement And Restoration Tips’ is an excellent guide for how to rebuild major components in a A100/C3/B3 organ.

I have a 1959 A100 and 1972 Leslie 145 and found the book an excellent resource for explaining how to rebuild the AO-28 preamp and 147 Leslie amp. I like the fact that you offer the rebuild kits and provides free schematics to go along with the book, what an excellent idea!

I really appreciated your appendix section where you explain basic electronics and how to use a solder iron to make good solder joints.

This ebook covers it all and I highly recommend it to all Hammond / Leslie enthusiasts.

Great Job!”

“Hi Pat,

Ever since the first M100 I used to play, Iíve been modifying and partly improving my organs. But I could use a guideline to seriously update the internals of my A100.

Your work is really helpful for everybody who wants to improve their organís sound, but is still in doubt whether they can do it themselves.

You prevent so many of the Frequently Made Mistakes, which saves time, money and most of all disappointment.

The best about it is the visualization, you understand the situation immediately, thanks to the pics. Updating the capacitors in the TG made a huge improvement to the tonal balance, recapping the AO-28 and the leslie amp made the sound so much opener, just what I was looking for.

Thank you! ”

"Hello Pat,

How to say thank you enough times for all the work you've done in my organ! I consider myself lucky that I have discovered your extraordinary talent very quickly after my A-102 and Leslie 147 purchase.

When I played it for the first time, I knew inside of me that something was wrong with the sound! But still, I was already in love with my new passion.

Today I can not stop myself from playing it. My Hammond organ is a part of me, an extension of my soul and a new flame to my passion! I actually found my instrument and thanks to you !

I am always impressed by the quality of sound that comes out of my organ since you did revived and restored it ! Again thank you so much for everything! My organ is now ready to go on tour across America ! !

Thank you ,"

This manual contains many invaluable "gems" about your Hammond and Leslie and provides you with a lot more knowledge and ability to fine-tune or customize your instrument to the way you like it to sound in minutes!

These secrets took me years of frustration, research, and trial and error experimentations to get the sound that I wanted!


Hammond AO-28 Preamplifier Restoration.

In this section, with the help of many pictures, you will learn which components are critical and need replacement in this unit in order to restore the performance and sound of your AO-28 preamplifier. 

You will also learn which components are most likely to fail under normal operation.

You will also learn that with the use of new higher-quality electronic components you will get a lot more warmth out of your organ's sound - believe me!

That's because manufacturers have had time to improve their product lines since the last Hammond B-3 quit the production chain back in 1974!

If your Hammond has the "Hums", Funny Noises, "Pops" and all those annoying noises, you will learn how to get rid of them and filter them out for a quiet and pure organ sound.

Leslie 122 and 147 Amplifier Restoration. That Smoking- HOT Leslie Sound Is Back!

You will learn, step by step with pictures, how to restore your Leslie sound to make it scream again. The Leslie speaker is the long-time companion of the Hammond organ. It is a VERY important component in the whole classic Hammond sound.

Even if the organ you play is in top shape and you play it through an original vintage Leslie . . .

...chances are that the sound and performance will be limited!

The classic B3 sound is a combination of the organ and the Leslie in top condition. You will learn how to rebuild your amp and make it sound better than new!

More warmth, more volume and cleaner without all the "hum"
that is associated with these antique amplifiers.

Leslie Dividing Network Restoration:

A Leslie speaker restoration without the maintenance of this this unit would not be complete.

The Leslie cross-over was designed to split the treble and the bass channels separately.

Again, due to aging, the original components drifted from their original value -- masking the true Leslie sound.

It is critical to check and replace the faulty components, otherwise your organ sound might be boomy or muddy-sounding without the definition your Leslie had when new.

Leslie Treble Horn Types

You will learn about different types of treble plastic horns, their different qualities,  and their contribution to the sound of your organ.

What kind of plastic horn do you use for your Leslie?

If you don’t know the answer you should find out, because this component makes a HUGE difference in the tonal quality of your Leslie sound.

Let me tell you a short story about it . . .

I met some "specialist" who laughed at me when I told them about the horn type.

Driven by their arrogance and strong desire to sound smart many of them prefer to stay in the ignorance instead of researching and experimenting it like I did!

You will also learn some simple tricks on how to adjust the frequency response of your top Leslie driver and how you could mellow your sound down for more warmth, for Country Blues or Gospel or make it sound brighter for Rock and Pop music.

What? A 31-Pound Leslie Treble Driver?

You will learn that you can install some treble driver that are a lot less fragile than the original V21 in your Leslie, that weigh 31 pounds but are very sweet sounding for a Leslie speaker.

If you have to compete with a guitarist with Marshall stack and need more power handling this is it.

This little-known driver also will give the organ a much thicker and fatter tone. The percussion will be more aggressive, the chorus vibrato will sound bigger, and the overdrive will sound sweeter too.

Do you like Paul Shaffer's sound on Letterman?

If you love the sound of Paul Shaffer's B3 on "The Late Show with David Letterman", you will be pleased to learn the secret he uses to make his B3 "bark" for that special full, open and fat sound!

You will also learn how to adjust the brightness of your Leslie treble driver to get just the perfect 'bite' that you want, and all that the easy way!

How to get more AM Leslie effect or "wha wha wha" by changing the organ settings just a bit differently without leaving the bench!

Easy Step-by-Step Way to Fix The Common Vibrato Chorus Problem:

One of the most common and very painful problem on almost all B-3's C-3's A-100's and similar organs is the huge difference in sound between vibrato chorus in their "On" and "Off" settings.

Let me explain . . .

You play with one of your favorite settings on non-vibrato, you select the vibrato. But suddenly, you pass from a dull, muffled and mellow non-vibrato sound, to a full bright and loud vibrato sound!

Everything comes to life and it sounds like a real volume and treble booster for the drawbars!

In many cases, it almost feels like you changed your drawbar settings! It is normal that the vibrato and chorus produce a brighter sound than the non-vibrato one because of the extra amplification stage in the preamplifier.

BUT it is not very musically pleasing when the difference between those two options is too noticeable.

In this manual, you will learn everything in a user-friendly step-by-step way with text, as well as pictures using your own Hammond organ service manual or a Hammond B3, C3, RT3 organ schematic that I will provide for you FREE.

You can’t read schematics?

No worries, you will probably turn out to be better than the ones who can, because this manual has been designed to be visual and easy to follow!

You will know exactly what to do to fix that problem and make your non-vibrato to sound almost identical and as bright as your vibrato position.

After this easy upgrade, you will notice just a small difference in the sound of both channels on your organ for a natural vibrato-chorus switching

The vibrato-chorus setting will be slightly brighter, but not much, so that the switching between these two settings will become much more pleasing and natural.

The vibrato-chorus position will just add that classic and sweet chime to your organ sound without acting like a drawbar amplifier!

How to Fix the Organ Volume Drop When The Percussion Switch “NORMAL” is ON - Step by Step:

Here again, you don't really need to know anything in electronics at all. I will help you fix one, if not the biggest, problem that almost all 3-series, A-100 series and D-100 series organs have.

It is the ridiculous drawbar volume drop when the percussion “NORMAL” switch is ON.

In fact, on stock organs,  the percussion volume increases, but the organ volume decreases dramatically, which make this feature useless.

This way, the percussion “ping” becomes too loud and the organ lacks all of its presence and bigness of sound.

This is why most organists never really used this option on these organs. This is also something that Hammond-Suzuki understood in feedback from their customers, and they addressed this problem in the production of new organs.

On the New B-3 as an example, the “NORMAL” percussion setting will NOT affect the organ’s volume in any way, retaining a fatter organ sound with an added aggressive “ping” attack.

I will show you an easy step-by-step way to fix this problem. After this upgrade, your organ’s volume will not drop when you use the “NORMAL” percussion volume.

This is a pleasant feature you can also have on your older Hammond organ. This upgrade will give you much more sound creation possibilities and it will change the way you use the percussion!

Percussion Improvement Part 2
Do you prefer a softer sounding "ping" like on the older 3-series organs?

Or maybe you prefer the aggressive percussion sound found on later B-3's?

Once again you are the one who will decide, and I will give you the information to perform the percussion volume adjustment on your organ.

This will be particularly useful for you if you play a Leslie with a modern treble driver in it. These high efficiency drivers always tend to make the percussion much louder than it should normally be.

Fixing the Non-Working Drawbars:
This is something very easy to fix and perhaps some of you already know how to do. But because it is a very common problem on all Hammond organs with drawbars,
I had no choice to include a section on how to perform that in this manual.

Step-By-Step Way To Fix Your Hammond B-3 C-3 R-T3 and A-100 Keycombs For Less & Save Hundreds of Dollars.

The manual will take you by the hand and it will teach you step-by-step how to restore your keycombs for close to nothing instead of the expensive alternative of buying other used key combs.

I will guide you step-by-step not only with text, but reinforced by pictures that I took for you on my own organ.

I know that the vast majority of people are not technicians so my goal was to write a guide that a 5th grader would be able to use without problems, and apply the information for him/herself!

So with all the text and images that are in the book, anybody would be able to restore his or her keyboards!

This manual will teach you how to restore your keycombs and give you the touch and feel just as if they were back to their original new condition.

Imagine yourself playing on a solid keyboard that is firm, or one that makes NO annoying plastic noises when you play it!

I remember how I felt after my key comb restoration back in 1997 and let me tell you this: "It felt great then and it still feels like that every time I play my organ since the last 11 years "

Did I tell you that I play Rock music and I am not very friendly with the keyboards? The first instrument I learned as a child were the drums, and I find it still shows in my organ playing style . . .

Deeper, stronger and louder bass on the pedals and fatter bass presence on the keyboards is what I have on the menu for you in this reference manual.

Would you like to get more bass and fatness out of your organ?

The book will describe 5 ways to increase the bass response on all B3s C3s and A100 plus all D100s series.

No wonder many organ parts suppliers are offering bass booster units for Hammond organs! Because it is a know fact that they lack bass.

Well, with the information included in that section you might potentially put hundreds of dollars in your wallet by NOT spending on one of those devices.

This works particularly well on B-3s C-3s and RT-3s from the 1950's; and the other tricks works for ALL models starting from 1955 thru 1975.

We will take a look inside the preamp and I will structure the explanations into simple steps along with diagrams and pictures for an easy understanding.

This manual will explain 5 different ways to get more bass so you will have the option of using just one technique or combine all of them together to get the most thunder out of your Leslie!

How to Fix That Dull & Dark Sounding Organ To Make It Sing and Scream Again
If your organ is dark, mellow and muffled-sounding without the fresh drawbar definition and clean, pure tone, and brightness without any inductive humming-

Then you will know where to look for in order to increase your organ's volume and restore the upper midrange and treble output to make it sing again just like it did when it was new!

Due to component degradation, the tone of the organ will change dramatically and you will hear that all-to-common common Hammond B3 humming problem.

This is also useful for Pre B-3 organs like models: B-2, C-2, BCV, BV, CV, BC, M-2, M-3 and all the way back to the first model A.

How to Get a Pure Shime Out Of Your Vibrato & Chorus Sound
There are a lot of Hammonds that suffer from a very dull and muted vibrato and chorus sound.

Again, because the aged component have drifted from their original specs, this will affect the quality of sound of your organ. 


I have experimented with components and value in this field and I have found, and will share some fresh information to help you get the optimal sounding vibrato/chorus that you can get.

Hammond Tone Generator Calibration & Fine Tuning:

This will probably be the most exciting and
fascinating chapter of this work!

In fact, it is the last procedure in the organ restoration process but essential in getting a great and perfectly sounding system.

We like to call this procedure the final "Blueprint" of a newly restored Hammond and Leslie speaker.

Many "Hammond experts" and shops will never even consider doing this step, which is crucial in any restoration project.

You will discover the secret we use to get a superior sounding instrument by recalibrating the tone generator, either to match with the frequency response of a Leslie speaker, or an easy and safe way to recalibrate your tone generator to a new curve that you prefer!

So many mistakes has been done in this regards by those before us, which is why I have decided to offer you a step-by-step guide to help you fine-tune your tone generator the easy and safe way.

Create a Graph that Represent Your Tone Generator Calibration Curve

Hammond Tonewheel Generator Calibration Curve Graph

No one ever released that kind of information before! 

You will be amazed by this tool that I will provide you to create your own unique customized graph made especially for your organ.

This will show you exactly how your tone generator is calibrated! This easy to use software that I provide you for free will be a great way for you to visualize how your tone generator is tuned in comparison with other organs!

You will have the evidence and proof that explains why each Hammonds and each organ age group have different sound.

Indeed, depending on the  year the instrument was
manufactured, similar generator calibration curves were observed during the production years.

Finally you will learn the secret about my "Blueprinting" process that is proven to give you a Hammond and Leslie that really sound as sweet as the voice of God!

This process is not only fun, but it is very rich in information about your unique Hammond.

You will learn all the tips that I have discovered during the last decade about generator calibration and how it can be easy to improve the sound of your Hammond and Leslie duo by using my techniques.

Believe me, I have made a lot of mistakes along the way, but that helped me to create a method that is now efficient fun and easy!

In a very short time, you will learn all the tips and the tricks that it took me years to discover. All this is made easier for you with many pictures and schematics that I have created especially to help you in your "Blueprinting" process.

For this chapter, you will have access to a private section for customers only on the website, where I will give you FULL access to all my favorites resources and downloads!

But Wait...



What? You Thought That Paul Shaffer's B3 Sounded Great?

Paul's organ on the Letterman show sounds pretty good but I can show how it could be improved and how you could get a better sounding organ than his! 


YES for sure!


If you listen to the show you will hear that Paul's organ has some very high pitch shrill response in the high tone generator notes. This can be heard right on TV!

Tube Substitutions:

I will also speak about some very cool tube substitutions on your AO-28 organ preamplifier and also your Leslie amplifier! Nobody ever released that kind of information to you before!

More classic Hammond B3 Growl:

Would you like to get some more Hammond growl faster, or get that fat bluesy sound? I am not talking about the trimmer capacitor here, but just a minor and easy modification on your amp.

More Pedal and Keyboard Bass:

What about more bottom on your organ? If you like that deep and fat bass presence you will be pleased ! I promise that you will put the thunder in your Leslie.

More Definition:

Get a pure sounding organ with a razor-sharp definition and tone. Perhaps you think that your organ lack its definition and it is too muddy - especially in the lower range of the manual.

Perhaps you would prefer your treble driver just to "float" over the bass speaker when you do some power glissandos? I know a trick to achieve just that in 2 minutes!



Why Your Book is Valuable You Might Say?

First of all, imagine all the savings when you can perform the work on your own.

Not having to move a 400-pound organ is reason enough! Or getting a van or a trailer to bring it to a technician, who will probably charge you a premium labor fee to upgrade, fix or maintain your organ, are other reasons.

Just to give you an idea, here are some price you should expect to pay a technician when it's time to rebuild any of these components:

- AO-28 Organ Preamplifier restoration: $450.00

- Tone-wheel Generator restoration: $500.00

- Leslie 122/147 Amplifier restoration: $350.00

Total for just 3 units: $1,300.00
and it's not over..

Price of this reference manual:
$47.00 (at least 26 times less expensive).

The knowledge you receive, priceless.

These prices are applicable only when your organ is already in the shop so I haven't included a van rental or trailer rental, nor your time and effort to move that elephant!

Now guess what . . .

Even though you would prefer to pay to get your organ to a tech it would not guarantee you a better sounding organ...

because most techs ignore how to get the best out of these instruments and they ignore the tricks and tips that I am about to share with you!

Don't look around to find a piece of work like this one . . . I've already checked. This Handbook is truly unique.

That's right!

There is absolutely no publication anywhere on this subject that are designed and written for the non technicians.

As you already know, we play music to express our emotions and feelings and we use the organ as a tool to communicate those emotions.

When the organ doesn't scream or doesn't have the punch you need how can you express yourself?

Most B3s today just don't deliver because of many technical problems. Not only is it boring to play those instruments but it can be very frustrating, especially when you know what you are missing.

Remember some B-3’s are now 53 years of age! In 2008, would you expect your ’55 Cadillac to perform like it did when new - without any maintenance?

The B3 and similar organs will need a little attention and maintenance to make sure they will perform as good and, in many instances, even better than new.

By giving yourself the instant gift of knowledge you will save yourself from the same frustration I went through in the past!

The feeling of control over the instrument you own, and being able to get the sound you want, will be easier when you know what to do and you can know all that, if you order your copy . . .

When I consider the energy that I have invested to discover what I know today, I realize that it is not only valuable but priceless. The time and money I have invested will certainly benefit you.

You will avoid having to make the numerous long distance calls that I made to talk to reputable Hammond technicians across the country; or the travels back and forth to the electronic shop to purchase different components for trial and error.

The online chats with some Hammond technicians. All these efforts are packed in this manual and can be revealed to you in a beautiful book that has been professionally edited!

So for the ridiculous price that I am asking, the quality of information that you are getting back, plus the money and time that you save -- you are making a fantastic deal!


Ten years ago I would have jumped at the opportunity that you have in front of you right now . . .

Because it would had saved me a lot of effort trying to discover all that information on my own. 

This Book will reveal gems to you that took me years to discover and to perfect.
