Question Push pull pots on JP

[PaoloGilberto]

Hi everybody,

I want to ask your opinion about push pull pots on JP.
I'm not good at the tech part, so will my ideas have any possibility to become reality ?
I was thinking installing 2 push pull pots (one replacing the vol pot, one the tone pot) .

all this to have something similar with the 25th - vol pot for parallel , tone pot for series

so I will have the present switch config + config when pulled:
position 1 neck sgl coil only
center inner coil from neck H and bridge sgl coil from bridge H
position 3 bridge sgl coil from H

all this in parallel with the vol push pull pot and all this in series with the tone push pull pot

is this technically possible?

thx a lot!

I would be interested in this also.

there are a couple of ways that you 'could' do this different. One being with a rotary switch and a push/pull tone control:
5-position Rotary Switch | Allparts.com
25K Push/Pull Pot | Allparts.com

The other with having a 5-way installed by modifying the existing 3-way switch hole.

I loved the tones of the 25th Anni but bonded with the JP6 for the playability, feel and piezo option.

I am interested in my first idea if possible, any help my friends?

Steve, that 5 position rotary switch fits in the place where the magnetic switch is now?

so once again I ask for help. if no one has a suggestion I will aks CS about this

Paul- I'm not sure exactly what you're asking. You mentioned having "sgl coil only" but also series and parallel. Single coil only would be a coil split, not a series/parallel thing. There's no way that I can see to have the default wiring be split coils and then have one pot to put everything in series, and one pot to put everything in parallel.

In general though ...

To switch each pickup from series to parallel, you'll need a DPDT switch - 6 lugs (what a usual push/pull pot is). So you would need one push/pull pot for each pickup. To do them both at the same time you'd need a 4PDT switch, which I've never seen as a push/pull pot. (It's used as the pickup selector switch on the Petrucci - 12 lugs.)

So- if you're going to use push/pulls, you'll need to wire one up for each pickup. Doing this is going to require changing the wiring to the pickup selector (it grounds coils in the middle position, this will conflict with the series/parallel switching and you'll end up with no output).

The easiest way to do it is to wire the pickup selector as a regular 3-way switch (bridge, both, neck) and have the push/pulls determine whether the p'ups are in series or parallel. The middle position would thus be the [series bridge] in parallel with the [series neck], or the [parallel bridge] in parallel with the [parallel neck]. You won't be able to get the one-coil-from-each-p'up in the middle that you normally get with the Petrucci. But having the p'ups in parallel gets you a certain amount of chime so you might be happy with that.

If you really want split coil sounds, the other option is to use another 4PDT on/on/on toggle. With it, you could put both pickups in series/split/parallel at once. If you were willing to lose the tone control, you could probably fit it in the same place. (I don't think you'd want to drill a hole for it.) It's the only way to get the split sounds as well as parallel.

Hope that helps.

many thanks beej.
As I anticipated what I was thinking it is not technically possible.
so your suggestion seems a reasonable one ...I'll keep that in mind.
any idea for the coil split? how will the new configuration be like?
can I keep the present config and have for ex inner neck coil/both inner coils/inner bridge coil?
if not what else do you suggest regarding wiring and having sigl coil with the coil split?

thank you ,

paul

PS: I've found this on the search here on forum regarding my Q
"all humbucking tones when the tone pot is pushed (including both hums on like the BFR in middle position) and all single coil tones when pulled (with the stock middle position still intact)." but can the stock middle position be the same?

The easiest way to do it is to wire the pickup selector as a regular 3-way switch (bridge, both, neck) and have the push/pulls determine whether the p'ups are in series or parallel. The middle position would thus be the [series bridge] in parallel with the [series neck], or the [parallel bridge] in parallel with the [parallel neck]. You won't be able to get the one-coil-from-each-p'up in the middle that you normally get with the Petrucci. But having the p'ups in parallel gets you a certain amount of chime so you might be happy with that.

Coil splits are pretty easy. You can wire up a push/pull that will split the bridge & neck, and leave the middle in the stock position (so it's the same regardless of whether you have the split engaged). Given that it's pretty straight-forward, I'd start with this.

And yes, you can wire it up a few different ways. You could have the HBs not split in the middle position until pulled, or you could get the stock wiring in which case the middle position would be unaffected when pulled.

The less wiring you have to do, the better I'd say (unless you really like messing with it). I'd suggest figuring out what you really need and going from there. I can give you a hand with the wiring, let me know and I can try and make you up a diagram, etc.
