SOLVED Mystery octave fuzz

[PunchySunshine]

My buddy handed me this pedal needing to be fixed, no clues other than it doesn’t work. The tranny on the far right was missing so I subbed in a 2a2222 as that’s what was on the other side and she’s alive. Doesn’t sound great and I think it’s the terrible Amazon 2n2222 that drift down hfe from 135 to 104 but I’m not sure if I even have the right chip to begin with. By any chance does anyone recognize this strip board for an octave fuzz?

Thank you O fuzz lords! Now it still sounds like shit but the proper kind of poop!

As a thank you, my buddy gave me a small bag of Russian mp-20 germanium’s from ‘77. I’ll be happy to share some with both of you for helping me identify that tagboard (if you want some)

THIS ^ is why this is the greatest board on the 'net — the people here. Generosity of not only sharing information and ideas, but also parts, PCBs and other tangible items, etc.

I love this place.

Rock on, folks!

Please don't send me any transistors. IYKYK.
But I'm glad you got it working!

Not that I buy transistors from Amazon, but what’s the story there? Are these normal TO-92’s?

I'm glad I didn't have to use them in the pedal! The missing chip turned out to be the in venerable mpsa18, which I had multiples of in stock from verified source.
