I looked around and this seemed like the best place on these boards to ask, so here. On my guitar there are two single coil pickups, one in the middle and one at the neck, and one humbucker. The pickup switch has 5 positions that work how you might expect with each pickup having an independent position and two combined positions in between the 3. So here's what the problem is. On just the humbucker setting, there's no buzz. On the setting that combines the two single coils, there's no buzz. On all three other settings, there's buzz. I don't really get how the two single coils individually buzz loudly but when combined are completely silent. So can anybody help me out on this? I don't get how this can happen. What can I maybe do to fix it? Could the problem be in the actual toggle switch?
