GregP Posted March 31, 2017 Report Share Posted March 31, 2017 End goal: EMG 89 and 81TW, 2 Volume, mode-switchable ("coil-tappable" but not exactly) via push/pull on the volume knobs. What I have - two dual-mode EMGs, an 89 and an 81TW. Their respective wiring is the same. - two push/pull 25k pots, and a normal 25k pot. I have an appropriate capacitor to use one pot for tone if need be - the older incarnation of EMG wiring... the pickups themselves have the quick connector end, but the other end (and the pots) are not quick-connect, so I'll need more or less traditional wiring diagrams. For all intents and purposes, the quick-connector is a pickup-changing convenience, not a wiring convenience. - a Gibson-style 3-way toggle My desired approach As mentioned, I would go with 2 independent volumes (NO tone), with each pickup hitting a push/pull-equipped knob for mode-switching ("coil-tapping", but not exactly) duties. HOWEVER, my understanding is that with "typical" wiring, in the middle position, you can't "blend" the way you might think. So you have to use a Jazz Bass-style wiring, which I THINK is the kind of wiring used in one of my samples below. Sanity Checking needed! I believe I have hacked together some information, but truth be told it's kind of just trusting that my superficial understanding of things is enough. I don't TRULY understand what happens in a potentiometer and I'm taking EMG's word for it on how to wire up the push/pull. Speaking of which, for the push/pull, the main diagram I come across is this one: Is it a proper assumption that the empty lug is what will get wired up to the switch? There was no one exact diagram (if you find one or know better ones, let me know!) but I did come across this: Here's where the sanity check comes in! Using this diagram as a jumping-off point, my thinking is that I substitute the white that's coming directly from the pickups to being the output of the push/pull. Then I bypass the tone altogether, sending the switch output directly to the output jack. Assuming my ability to mentally re-arrange things in 3D space, I believe the diagram also confirms that the "empty" lug from the first diagram is indeed connected to the switch (the orange and blue in the diagram). So... any takers on a sanity check? Including confirmation that the volumes will not suffer the "in-between" problem of allegedly independent volume knobs? Any opinions on a better setup that uses only 2 knobs? I'm not totally against going master volume plus tone, but that option had me even more confused (and isn't my preference anyhow) when I went looking. Thanks!
