Creepy Fingers DoomiDrive

Here's a cool dirt box from Creepy Fingers. It's essentially a modified Fuzz Face with an output buffer. The Bottom control pans between 2 input capacitors and offers a wide range of tones throughout the sweep. Originals used 2SC859 transistors which can be hard to find and have a BCE pinout, but I've also laid it out for CBE pinout transistors. For Q1-2 try 2N5089s and for Q3 try an MPSA18, but socket and experiment.

Creepy Fingers FuzzBud

Here's a great sounding one-knob fuzz from Creepy Fingers Effects for your FuzzFriday. It's based on the fuzz section of the Colorsound Fuzz-Wah and follows the basic structure of the Fuzz Face, just with a fixed resistor in place of the fuzz control. Shouldn't be hard at all to fit in a 1590a enclosure.
