These are 1:1 replicas of the original Rams Head Big Muff Pi V2 PCB's  - using modern FR4 material and a black finish.

Controls:
Sustain
Tone
Volume

Notes:
- Remember to socket your transistors
- This is a POSITIVE GROUND board - do not daisy chain it with your standard BOSS style negative center pedals unless you use our inverter board and wiring in the document.
- This is a big board (same as the original) you'll need a 1590BB (min) and careful planning!

 Note: This is for the PCB only, you will need to source your own components
