Circuit Board for the Griffin Effects Multiboost project.
Based on the Electro Harmonix boosters. The circuit board is designed to build one of four circuits. The LPB-1 Linear Power Booster, Screaming Tree Treble Booster, Mole Bass Booster, and the Muff Fuzz. With some added switching it's possible to switch between a few of them. There's lots of room for mods here to by combining the different circuits!
