ParticipantI will do that. But right now I have another side project. Going its hunting season here and I process game on the side and had a elk brought to me so it’ll be a few days before I get to it. Thanks for the help so far.

ParticipantOk so reversed and changed out the A92 to n3906 and actually the pin out for the 3906 is the same as the A92 so with doing that the purp side is fixed. But started working on the tone tweak board and I have tried to test everything with volts and continuity. Found I didn’t have volt passing through R1 and R12 so lifted one leg to test each couldn’t get a reading so replaced both. I THEN did my bench amp testing and I have through signal but as soon as I hit the switch I get nothing still. I AM at a loss now. Lol thank you for any help.

Thank you sir I unsoldered it from the other board to further test but haven’t got much further I will reverse that next and see where that takes me.
Mikey
ParticipantOk well I will un solder the breakouts and start with the purp

ParticipantOk thank you guys. Whole new set of issues now on this build. So I am daisy chaining the tone tweak into the purp I get no signal from the tone tweak but I do get signal from the purp but gives the opposite effect. It cuts instead of bosts I also modded the grit with a A10k potentiometer instead of the trim 10k. The transistor I used is an A92 it read 137 hfe on my mm. Not sure if that is the issue or not but just trying to figure it out I have power to everything and I have tested for continuity to both boards. But that’s as far as I got.
Here’s a pic of the build.

ParticipantPurp build not purple

ParticipantNext build will be the purpetrator its the purp board with the tone tweak.
Mikey
ParticipantEverything is test through my bench amp before and after it goes into the enclosure to avoid to much hassle, of taking it in and out to diagnose. Issues . Learned that the hard way.
Mikey
ParticipantAlright here are pics of the finished build
