Clone of the legendary Tube Screamer and most commonly used and reproduced guitar pedal clone. This one has an FAT option which can be used to choose between the frequency range of the clipping stage.  Therefore making the tone suitable for bass guitar tones with a LOT of BALLS.

Add another footswitch to have total control or just use a SPDT switch. Easy build! This is a PCB bundle which includes the 3PDT switch PCB for true bypass wiring as well. No tedious wiring! Simple and effective!
