    Pro-ten green side very little gain

    Pro-ten green side very little gain

    Thanks again for trying to help. Gain knob acts pretty much like a volume control. The highlighted resistors are the correct values. Confirmed by bands and DMM

    Pro-ten green side very little gain

    Thanks for the reply. My iron sits around 790. The green is producing no gain. It works like a boost pedal.

    Pro-ten green side very little gain

    Thanks szuk, it appears they are the same. I also have j112 and j113. Im fairly limited in my knowledge, but I believe it is not part of the distortion matrix, maybe a buffer?

    Pro-ten green side very little gain

    Anybody have any thoughts? I got a shipment in from BLMS, so now have the proper pots in. The pedal works perfectly except for not having any appreciable gain on the green side.

    Pro-ten green side very little gain

    Blue side sounds absolutely glorious. 10/10. Green side has almost no gain. Volume and tone work as expected. I have built a few of these, so I know something is amiss. Really scratching my head. I believe all components are correct except a few I didnt have: 2n5457 instead of j201...

    Newbie first build gone wrong

    Are the back of the pots insulated in any way? They can short against your solder joints.
