What’s this?

Funny story. Someone emails me today and says they bought a pedal from me some years ago, it' has be 10 maybe more. They really like it and want to know what circuit it is. I have know idea!






Looks like 4 Si transistors.  Volume, tone, gain, and a switch.  The transistors look like some BC108's that I have in a bag.

Silicon Buzzaround?

I figured it out! Looking through my old notebook I found this schematic of a Si Tone Bender by a user Mictetser on that other forum.



Here's a a link to the thread over "there" https://www.freestompboxes.org/viewtopic.php?t=7767&hilit=Silicon+tone+Bender

hmmm, very interesting.

i doubt ill ever forget what pedals i have build and whats inside which enclosure
partially because i use fairly unique circuits that have been tweaked for a while before me being happy about it, and partially because i have build less than 15 complete pedals.

cheers
