Wonderful! Thanks for the quick response. Cheers!

Hey everyone! I saw that some layouts show a 3362P trimmer but have 5 through holes on the board. Should this be something other than the standard 3 leg trimpots I have been using?

How hot are those 109s?

The tone/spectrum control doesn’t currently have any setting that gives me usable presence or top end which was what first set off my alarm. I have tried with a Les Paul and a Strat. The Strat has fairly low output pickups but it was still pushing this bad boy into a lot of drive.

@PedalPCB how similar would the nobleman schematic be to the Pro-10 Green? Close enough for rock and roll troubleshooting?

Dangit! I thought we were onto something.

Agreed. The Nobleman schematic shows this going into Q1.

Just took the MM to it and here is what I am seeing. Something looks up with Q1, yeah? Voltages IC1 1 -4.48 2 -4.48 3 - 4.47 4 - 0 5 - 4.46 6 - 4.48 7 - 4.49 8 -9.02 IC2 1 -4.49 2- 4.49 3- 4.48 4- 0 5- 4.42 6- 4.48 7-4.48 8-9.02 Q1 2N5457 1 9.02 2 .24 3 0 Q2 2N5088 1 3.39 2 3.97 3 9.02

Interesting! I have almost too much gain out of mine. Maybe I need to double check my Q1 and Q2. I’m guessing you don’t have any issue with top end/treble?

Thanks for the help! They all “do” the task assigned to them *but* I have to have the volume pot all the way up to be unity. The gain pot goes from overdrive to almost fuzz which seems odd for this circuit. The tone knob gives me some top end back but it still pretty buddy. Only component...

Out of curiousity, what did you not like about the Pro-10 Green? I just built one too and at first thought I had an issue but on second checking, maybe it just isn’t my cup of tea.

Or I guess another newbie question…where would I be losing top end due to user error? Ground connections? Bad solder joint somewhere?

Happy new year all! I recently built a string of pedals and for some reason only this one is giving me trouble. It sounds like a wet blanket is over my amp as I have very little treble or presence with the effect engaged. Which capacitors/resistors would affect this element of the signal?

I appreciate the clear toggle troubleshooting steps. Those will definitely come in handy. I replaced that resistor and now I have MASSIVE amounts of output. Can’t thank you enough for the help! Lesson learned.

Thanks! Here is a picture of the top and bottom of the board. The toggle currently doesn’t seem to have too much impact on volume regardless of position.
