Greetings! Hope everyone is doing well through all the craziness this year. The issue I am having with the Polyhog is the volume output is very low all together and the volume pot works as expected (still not a lot of volume output) until maybe the last 1/3 towards max and it then starts to go the other way getting quieter. The bass knob does the same. It works until the last 1/3 then it seems to stop adding bass and starts to remove signal volume. The other pots seem to work as they should. Initially I thought a bad solder joint or I had a electrolytic cap backwards but everything seems to match up and I used a jeweler's lope to go over the board looking for shorts. Staring at the schematic I tried swapping out the op amps (IC1 and 3) but nothing changed. Any help on where to start testing or what the problem could be would be appreciated. Thank you!
