German Tooth FuzzVerified
Based on the German Tooth Fuzz
From the post
If you've got a bunch of NPN germanium transistors kicking around, this Fuzz Friday's for you. Here's Zzoyd's adaption of the Basic Audio Spooky Tooth for use with germanium transistors. The first 2 stages each use 2 germaniums in a Darlington pair, with the 3rd stage using either a 2N7000 MOSFET or an NPN silicon transistor (pinout is CBE on Q5 if using a BJT in place of the MOSFET). Trimmers are for biasing the Darlington pairs, so adjust till it sound right to you.
