Recently built up this JMK Bass Overdrive pedal as a lockdown project. Unfortunately there’s a fault and while the bypass is fine, engaging the pedal results in no effect, a very quiet clean signal and a constant high pitched tone. Volume control has a small effect, but gain and tone controls have no discernible effect.
I was a bit of a numpty and didn’t test the board before I wired it up....so I don’t know what’s at fault. Have replaced IC and transistors (as they’re socketed) to no avail. Only one LED is lighting, but it’s my understanding that’s bot really an issue with this clipping.
I’ll try reflowing the switch next, if no improvement, I’m not sure I have the inclination to unbox the whole thing to test the board lol....we’ll see.
Anyone want to troubleshoot it for me? 😂
