I have a 1975 Tele Custom. The wiring (from before I bought it) is a bit different from the published diagram. I'm wondering how the switching/controls are intended to work? Something about the tone was bugging me but it took me a while to figure out what. I traced out my wiring if that helps. Position 1: Neck only- works fine. Neck volume and tone controls are active, bridge vol and tone controls aren't. Position 3: Bridge only- works fine. Bridge volume and tone controls are active, neck vol and tone controls aren't. Position 2 is where I'm confused and it's a little hard to explain: Both pickups are active as expected, but either set of controls effects the entire output signal. For example, right now I have the pickguard (and neck pickup still in it) uninstalled to the side, and I have a string on the guitar, so only the bridge pickup can pick up that string. In the middle position if I turn down the neck volume, output still goes down. If I turn down the neck tone, treble decreases. The reverse is true, in Position 2 the bridge controls affect the entire signal including output from the neck pickup. So with only the bridge pickup having a string above it, the neck pickup's controls are affecting the output signal. I hope what I'm saying makes sense. It's not the behavior I'd expect. Very grateful for any advice or errors with the wiring. Here's a drawing of how this thing's wired, I don't see any errors but obviously I'm missing something. On the gray/black dashed wires, that's the braided outer layer.
