Bass FuzzDriveVerified
Based on the Bass FuzzDrive
From the post
Here's a cool bass fuzz designed by Derringer over on DIYSB. It's based around the classic DIY Bazz Fuss with built in blending circuit. Derringer mentioned that it might need a booster after it. The good ol' LPB-1 should do nicely. Just put it between the Blend pot and Volume pot. Here's the schematic.
