Welcome!
Looks interesting...

it appears that diodes are doing most of the distortion. Were you able to identify what type of diodes it uses for clipping?

Hey man!
I forgot to mention that the diodes are 3mm LEDs. The regular ones like what Boss uses for indicator leds. I didnt try modding the thing as it isnt mine. A buddy asked if i could give it to a common friend and somewhere along the way someone dismantled and traced it

. It has too much bass. And I want to know what it sounds like with.out the diodes.

Sadly I dont have it with me anymore. I can tell you its a double sided PCB with board mounted tube sockets and a board mounted step up traffo. Ill try to take some pics if I come across it again.
