Do you have one of the vintage Hammonds ?

Would you like to add some new features ?

Does it just not sound like it use to ?

Is your local music store trying to sell you a new one because the old beast is not worth fixing ?

Well......Don't you believe it !

The statement ........

" They don't make them like they use to"

does apply !

Most of the vintage Hammond Organs are worth more now than when they were new.

Aging of the components will cause the sound to change.

But the answer is NOW available.

These Solid State upgrades will bring the old beast back to the sound it originally had at the fraction of the cost of replacement.

With the upgrade kits for reverb, percussion, etc. you can now add features that were not available when they were new.

These kits come with complete, easy to follow, step by step instructions.

If you have any questions or problems we are always here to help.

VINTAGE HAMMOND UP-GRADE KITS

Does the old beast sound muddy, or just not as bright as it did? Does the sound seem a little distorted? Just not as clear as it did.

If the answer is YES then these solid state preamplifiers are the answer to your problem.

Over the years the components in the old preamplifiers would change values which causes distortion and loss of high frequencies.

One answer would be to rebuild (replace all the capacitors and resistors and tubes in the original preamplifier.) This is very expensive and time consuming. Not to mention the fact that some of the parts are just not being made anymore.

The better answer is to replace the entire preamplifier with the new SOLID STATE models shown below.
