Hey. I'm trying an ambitious project, but am having issues before the complex stuff comes in. Plan is to have an onboard distortion effect pcb wired into 3 out of 4 knobs on SG style guitar. Leftover knob is volume.

Intended wiring is pickups (humbuckers, confirmed to be working) to switch, switch to volume, volume to effect PCB, PCB to jack.

Started with a basic pickup -> switch -> volume -> jack and grounding everything (including bridge). This has given me an unreasonable number of issues. Both my dad and I are Flummoxed (in his words) as to why it isn't working.

Current situation is absolute silence. No buzz, pickups not picking anything up. Something is shorted somewhere but we can't tell where. Previous attempts have given us varying results including switch working but knobs not, everything working but lots of whistling, and even everything working but so much buzz (buzzing has been a consistent issue, sometimes it goes away when touching metal, sometimes gets worse).

The components are brand new, bought earlier today, except for the switch (came with pitbull kit, couldn't find switch at local store).
