Is this possible - Mag/Piezo A/B AND Coil Splits

[jshape]

I'm working on a LP-style project. I've got everything built and put together and it feels and plays great. Now I'm wanting to hot-rod the wiring for a wide range of tonal options. I've got a DiMarzio 36th Anniv PAF in the bridge and a Duncan Design HB103 in the neck (Not my favorite PU, but I had one laying around and I plan to use it split a lot, so I figured higher output might work out well). I've also got a piezo Nashville bridge and a Fishman Powerchip preamp. The Powerchip will take up one of the spots for a tone knob, so I'd like to have a master tone knob that adjusts tone for all 3 pickups - both mag humbuckers and the piezo. I also want 3 push/pulls - the bridge vol will split the bridge hum, and the neck vol will split the neck hum. The 3rd push/pull I want to be the master tone that when pulled will kill the humbuckers and activate the piezo. I'm not concerned about blending or running a stereo signal, so I don't think I'll need a stereo jack, but I could be mistaken. The 3-way toggle will just function like a standard LP setup.




So the questions are: is this possible? Can I have push/pulls that split AND a push/pull kill switch at the same time? If it is possible, any tips on a good place to figure out what the wiring would look like? Also, since I'm not blending the mags and the piezo, am I okay with just a mono jack?




Any help is appreciated. Cheers!

I did this with one of my LP clones

Used one of the tone knobs for a piezo volume

So I had three volumes and master tone

Wire to tones independent
Swap the "from pickup wire"
And the "to output jack wire"
On each volume so when you roll the piezo down it doesn't turn everything off

Or you can do a master tone and master volume for the magnetics and a single master tone and volume for the piezo
still wire the volumes independent

push pull for splits

Now that you mention it, that might be a better way to go. I This way I can have different tone settings running concurrently on the magnetics and piezo and not have to worry about getting to the tone knob when switching between the 2. Is it possible to have the 3rd push/pull set-up to activate the piezo and kill the magnetics when pulled and vice-versa when pushed?

I suppose it is just a few more wires

I prefer to just role down the volume on one

or use just a hint of piezo for clean parts
like a chorus
Little more chime

The piezo is a bit harsh on its own
I usually blend in a bit of neck to fatten it up

Oh and you will want to use a 100k pot for the piezo volume

I think 100k is what I have been using
Your Fishman instructions will say

Don't you have to use the supplied 9-pin output jack with the Fishman?

P.S. I'm not trying to cost you money or anything, but Fishman, themselves, have two new (reasonably priced) pedals that would be perfect for this app. If you use a stereo output jack, and wire the magnetic pups however you want, to the standard "tip" lug. Then wire the piezo system to the ring lug. Use a stereo output cable, and run into either of these would be sweet. And versatile.

More info on their page.

I can't edit above. Both of those are specifically designed to handle a TRS 1/4" cable input and manipulate each according to how you set the switches. I'm thinking of trying one for a standard electric.

That could be. I guess there's no reason not to use it, as I already have it and have used it when I've had the Powerchip installed in other guitars.

I'm just still mainly trying to figure out how to wire a push/pull pot to be an A/B switch between magnetics and the piezo.

Like this, but keep in mind, this will give you either one. Never both. And, you may want to extend the wires so that you use both terminals of each. In other words, piezo to both top terminals, "output" to both middles, and mags to both bottom terminals.

I prefer just wiring independent volumes
and rolling out which ever one I don't want
