Hello everyone, I am returning here after the OC140 part arrived and I was able to continue with this project. after I replaced GT402V with the correct part OC140 the pedal is working and it sounds amazing. So problem solved thanks to this community. Thank you for all the help. lesson learned...

Hello. It is a 402. Would the GT404B be a reasonable replacement instead? They are available at small bear “ Product Description NPN complement of the GT402B Take note of the pinout! Gain range of 80 to 140, some fairly leaky as NPN germanium often is, but still usable in BMPs, Fuzzrites, etc. “

I read someone saying they are possible replacement. Your question went right above my head. If what you are saying is the problem then it means I got the wrong substitution? I guess I need to do some more research on that. Thanks

I color coded white for input and yellow for out.

So if I understand this correctly I have to switch the position of b/c to fix the problem? With the center pin facing away from you which is the emitter? Thanks so much for this. I will post my findings

Dude. This is in Russian. Lol. Joking aside, I will research the original pins and see this item. Only worried because I did not leave much of the transistor pin left to switch them around 🤦🏻

The pot is not insulated but it is sitting high up not touching anything. I could not find my info on the original transistors to compare. I will review the components again to be sure. Maybe the color scheme are too close together or something. Any comment about the wiring? I’m not too...

Hello, this is the first pedalpcb board I build. I was having a lot of troubles with the wiring but this is now where I can't seem to advance further bypass is working. when on, led turns on (picture does not show LED because It is not soldered to the board) when on, with volume at zero, there...
