Tube Sound Fuzz

TSF case

. . . from EPFM (Electronic Projects for Musicians), by Craig Anderton. Rumor has it that the Way Hugh Red Llama Overdrive was based on this circuit, which is actually pretty simple and really easy to build.

The only mod that I did was to add a SPST toggle to switch in an additional input capacitor for more bass response. You can hear the difference in the clips.
