Effect Pedal Kits: 

The 

FET

 

Preamp

 is inspired in the legendary 

BOSS FA1 FET

 amp, a 

discontinued pedal made famous by The Edge. With this kit you have 

the opportunity to build a replica of this rare gem! The FET Preamp 

features a 

Baxandall 2-band tone circuit

 control that gives full 

control over the tone, avoiding the need for other tone shaping 

pedals. The FET Preamp is a very 

clean boost

 perfect to get a bit 

more of volume or help your tube amp to break up in a natural and 

warm way. 
 
The only improvement made over the original Boss FA-1 is the use of 

True Bypass switch

 to avoid tone loss when turning it off. 

 
The FET Preamp has the following potentiometers: 
 

- The 

LOW

 SPDT chooses between a flat response and a low cut 

Treble

 and 

Bass

 set up the equalization of the sound 

Vol

 acts as a master volume control
