fender amp modifications

These kits allow you to build an amp of outstanding quality and performance from a stock ‘donor amp’. They replace the preamp and driver stages with one of our designs, keeping the original power and output sections. Designs are listed out here as modifications, but are also available in build-from-scratch form. See our Semi-Custom Amp for details.

Kits contain fully bound instruction book, all components necessary to complete the circuit board, plus a footswitch.

 Features common to the following twin channel designs
Instant channel switching - no pause, no pop
Each channel with its own tone controls and tubes
Tube buffered Effects Loop
Upgraded Reverb on both Channels
Entire circuit ‘backdated’ to pre CBS technology
Dual Stage Master Volume for control of the whole amp


The following kits are for Fender Tube amps made before 1980 - these are the amps with 2 channels plus Reverb (and Vibrato). Twin Reverb; Pro Reverb; Deluxe Reverb; Vibrolux Reverb; Bandmaster Reverb; Showman Reverb; Quad Reverb and Super Six Reverb. We also supply the same designs for Reissue Fenders - see below.

Extensive Modifications for pre 1980's Fender tube amps

TEXAN DELUXE KIT - PART# ST6TK
The Texan Deluxe amp is our most popular Blues amp. Originally built for Stevie Ray Vaughan, hence the name ‘Super Texan’. A clean channel with the ultimate warm, full clear Classic Fender clean sound. Channel switching goes to a second channel and a warm fat ‘Fender on 15’ overdrive without rasp or Heavy Metal harshness. Lots of sustain while still maintaining killer punch and definition. It has all the Bass and Midrange missing from pedals and other amps. A ton of useable tone in the graduation between clean and dirty. By no means a one trick wonder.

BLUEROCK KIT - PART# TB6TK
A complete rebuild for the Blues/Rock guitarist. Again, a clean channel with the ultimate warm, full clear Classic Fender clean sound. Channel switching goes to a second channel and a high gain, super-sustain overdrive tone with the Hot Rod character of Boogie type amps and none of the disadvantages. Virtually endless sustain, crunch and big tone. Like the Super Texan but with an extra stage of gain!

ROCK HOUND KIT - PART# DM6TK
The Rock Hound is the dream Rock guitar amplifier! Two complete channels, each with two distinct personalities. The clean channel has the elusive and perfect early ‘Plexi-Marshall’ fat crunch tone, plus a Torres design Mode Switch to change to the crisp clarity of the classic Vox AC30. Two clean tones to choose from. Channel switching goes to a second channel with a giant, almost scary, monstrous high gain Marshall overdrive. Tons of sustain, crunch and aggressive big tone - think Hendrix. The Overdrive Channel also has a Mode Switch to switch it to the modern Mesa Boogie-like Dual Rectifier Tone. Brighter, with more presence.

BAR-B-Q BASSMAN - Complete rebuild for the Blues Deluxe/Deville and Hot-Rod amps to produce a 'boutique standard' vintage classic: Basically replaces existing PCB and all related components including pots and tube sockets.
264
Bar-B-Q-Bassman59 kit - is a complete rebuild of the Fender Blues Deluxe/Deville and Hot-Rod series of amplifiers. The result is a single channel classic in both tone and construction.

In effect, the existing amp is used as a donor. The cabinet, speakers, chassis, transformers, reverb tank and valves, all good components, are retained but the printed circuit boards are replaced by top quality point-to-point wired circuits driving chassis-mounted valves and all-valve reverb.

The result is a ‘boutique standard’ valve amplifier of vintage quality based upon the classic Fender 59 Bassman. The essential circuit is standard but we have added all tube reverb on footswitch and high gain input with its own drive control. The added features in no way dilute the vintage tone but are there to take advantage of the control features available on the donor amp.

The upgrade is very successful but fitting the Bar-B-Q-Bassman is technically challenging. The upgrade is irreversible and requires a good background experience so it is not a first time project.
