Would anyone out there have a schematic for a '78 EH Muff Fuzz - it's the small one that can be plugged into an amp?
My buddy needs to know how to attach the positive and negative leads from the battery.
You can check for schemos on diystompboxes and freeinfosociety, but the battery wire polarity is an easy one- try it one way, and it either works or it doesn't. If it doesn't, swap them. No harm done in the process.
