| can we help? | |
| Hi, I recently picked up a Digitech HM2 (HarmonyMan) pedal and am having many issues with it. The blend knob is non-functional. Also, the effect only engages on preset 3 which is fixed to full blend. Every other setting doesn't work. I replaced the blend pot but this did not fix the problem. Here's a video of the pedal with issues: Any help would be greatly appreciated! Best, Max Kutner |

If you want some help from us it would be a good idea to share pictures of the inside of the pedal as well as a schematic if you can find one.
Here are a few pics of the circuit as is. The part which was replaced is that green pot in the first few photos. I've included front and back of both boards though in case anything else jumps out.
I haven't found a schematic yet.

The solder joints on that pot are cold. Try removing some of the solder, then reflow them so they look nice and shiny and try again.
Gotcha! I was hoping that maybe the case.
I have a suspicion that maybe I damaged one of the pads when I extracted the broken pot. Is that possible and if something was damaged, does this means that the part is no longer able to be installed properly? Forgive me if these are stupid questions.
