I have a guitar with two pickups and a three way switch. Which the switch is set to either the neck or bridge pickup, it works fine. When the switch is set for both, only the bridge pickup comes through. I can't figure out where the problem is, since both pickups work solo, but not when joined. BTW, I checked the switch for continuity, and the circuits in all three positions seem fine.

  • How are you verifying that only the bridge signal is getting thru? Are the two pickups of the same impedance? (If not, one might overwhelm the other). If you identify your guitar as well as the pickup types, and preferably show a detailed circuit diagram, that would be helpful. – Carl Witthoft Nov 5 '18 at 14:15
  • May I recommend editing the title of this question to be more specific about what the problem is that is confusing? I don't know enough about guitar pickups to do it myself, but it would help other people find this question and its answer. – General Nuisance Nov 10 '18 at 5:08

If the switch shows proper continuity in all positions and the pickups are definitely good it sounds like a ground issue. Check a schematic. If the schematic checks out, un solder the switch from the pickups, clean all solder off switch, snip the pickup wires clean, restrip and tin the wires, and resolder the pickups to the switch. If that doesn't work, you can double check the pickups by switching and rewiring them. If you have the same problem, it's the switch or the way it is wired. It's either the switch or the wiring assuming the pickups are good.
