A cool kit to turn a Silverface or Post CBS 
Blackface Fender in a pure vintage sounding amp.
Tested and loved by musicians for 12 years!

This is an application of Torre patented technology to get a better vintage sound than even the best vintage amps. The new tone is warm, rich, and fuller than the stock amp with a definite "vintage" blue/rock tone.

This is not the simple bias modification found in some books. This is an actual modification of the circuit in the amp to reproduce the tone of an old amp.

Easy kit, 20 - 25 minutes. Moderate soldering skills, no extra tools or test equipment needed. Ability to follow instructions. Illustrated (not a schematic)

This kit is for old Fenders made prior to 1980, not the reissue amps.

All the amps listed have the same circuit. There are minor appearance differences over the years, but the kit applies to all of the amps.
