A silicon transistor based fuzz is all you need to get a sound like Queens of the Stone Age.
This is designed to fit easily in a 1590A. With a low part count, and one 9mm onboard mounted pot, this build can be done in an hour.
Don’t want it in a 1590A? No problem. It works just as well in a 1590B or bigger.
