I’m coming to the end of of my first partscaster creation, which is a thinline tele-style with dynasonics and a kind of unique control layout that I’m on the verge of cracking, but I desperately need help to bring it over the finish line. As my friend says, it’s a Tele that thinks it’s a Gretsch. Here’s the dream: master volume, master tone (not pictured above—it'll be on the lower horn), and independent volume controls that are only active in the middle position. So in positions one and three, it’s basically tele—all neck or all bridge, only affected my master volume and master tone—and in position two, it’s a blend of the two that I can dial in as I like with the two independent volumes, and it’s still going through master volume for easy, one-touch volume adjustments that won’t mess with the balance. Here’s the diagram (very layman-like, but that’s what I am), which utilizes a 3-way super switch; for whatever it’s worth, I have simplified the way the two volume controls return to the switch, so that they now each come back to their own “2” terminal, and then a jumper joins the two common terminals (the problem I’ll describe existed both before and after this change): Here’s the problem, which is solely in middle position: with both pickup volumes down, I still get bridge output. If I then turn up the bridge volume pot, the output gets a little louder, and I think the tone changes. I’m testing things by tapping on the pickup magnets, so I can’t be 100% what the effect is, but what I instinctually think is happening is that I’ve got bridge signal always present, and when I roll up the pot, I’m adding a second bridge signal to it. For what it’s worth, this is the second time I’ve wired this up, with different pots the first time, so I don’t think it’s faulty electronics. Just, maybe, a faulty concept. Also for what it’s worth, if I disconnect the wire from the bridge volume back to the switch, I get nothing from the bridge pickup in position 2. So that always-there bridge output is not bleeding through the switch; it definitely has to do with the way it’s wired. More weirdness abounds: the bridge pickup is significantly less buzzy than the neck pickup. I guess that might be to be expected if those two bridge signals are working together to cancel noise. BUT the other thing is that if I roll up ONLY the neck pickup, that always-present bridge output diminishes significantly. Is that weird? I hope not. I hope one of you experienced electronics guys/gals will say one of two things: That’s not weird; you’ll always have this issue because of [insert electronics concept here] and there’s really no way around it. That’s not weird; you just need to [insert wiring fix here]. So, hive mind, whaddaya got?
