"Serious Tone for the Serious Musician"

Designed for pre-80's Fender tube amps and Marshalls (JMP, JCM 800, Super Lead, Plexi reissues).  These are some of the same mods that we do in-shop, but are pre-packaged with parts and easy to follow instructions.  Very simple to install and an immediate and noticeable improvement in performance and tone.  Kits can be used together for maximum effect.  If you have any questions regarding the kits and your specific amp, send us an e-mail.

A must for all Silverface amps and even offers improvements to Blackface models as well.  Gives the gain, warmth, harmonic content and overall great tone of the older Fenders.  Additionally it balances out the drivers circuit and tightens up the bottom end that plagues many old amps.  Extremely simple to install.

Take out the lousy, tone-sucking caps that your Silverface came with and give yourself a well deserved tonal upgrade.  Kit also works on Blackface models as these caps will outperform the originals.  Easy to install and works great with the Definitive Blackface Kit.

The amount of midrange on a guitar amp is critical to obtain the tone you want.  This is a great sounding, switchable midrange boost that will give you a fatter, dirtier tone with more power and sustain.  Put some crunch in your chords and singing sustain in your leads.  Let's you easily switch between the boosted sound and the stock sound.

Same description as above, but designed for Marshalls.

This kit has a 5 different midrange boosts which allows you a great deal of control over the midrange quality of your amp so that you can dial it in the way you want.  Also has a bypass setting so you can retain the stock, unboosted tone.
