The Pile O' RATs is the GUP Tech take on the classic Proco RAT Distortion pedal.
This version comes with 3 clipping modes (8 Toggles), center position is LEDs clipping, right is the classic Diodes, left is dual diodes stage (more clipping).
A sweep knob has been added (Classic RAT mod) to move the mid peak (let it at 0 if you want the original RAT tone).
Come stock with an OP07 but can come with a LM308 on demand !
