Happy Fuzz Friday, everyone! This week I give you the Earthquaker Devices Tone Reaper. This got traced over the Tagboard Effects forum, so thanks to Galapagos for doing the leg work. It's based on the 3-knob Tone Bender, with the darlington pair of germanium transistors simplified into a single high gain silicon transistor. In some respects it's similar to the D*A*M GB-83 Greasebox in that respect. An AC176 is used in the originals but others may work. Socket and experiment as usual. The tone control has also been changed to a BMP tone stack. I redrew the schematic for reference:
