There’s no shortage of PCB offerings for a Big Muff, but I’ve tried to make a board that could be used to build any variation or clone out there as well as incorporating a number of mod options. Here are a few of the features:
- Optional “Presence” or midrange control (more info at AMZ). If you choose not to use this control, the Tone pot has two possible orientations so you can still have a symmetrical control layout.
- Extra pads for clipping diodes, allowing you to easily use LEDs or just about anything else
- Choice between two different gain recovery/output stages: “classic” or JFET (like in the BJFE Fire Red Fuzz)
- Space for large 1uf film caps where appropriate, allowing you to build any historical variant of the BMP
