JP6 With PCB - Anyway to simply change middle position to both humbuckers on series?

[yah]

I recently got my hands on a 2014 JP6 PDN Neptune Blue that's pretty nice. I have an electronics / pickup switching question that I was hoping someone could answer.

In the middle position the pickups are wired in serial. There is a significant drop in volume when playing clean guitars when I switch to the middle pickup, and I personally enjoy the sound of 2 humbuckers on and in series for the middle position.

This JP has a PCB on the toggle switch like this one:

Is there any way to simply alter the wiring so that the middle position is in series with both humbuckers on?

FYI - I contacted EBMM customer service and their reply was to purchase a push/pull pot and wire it like a BFR. Just wanted to see if any EBMM gurus had any simple solutions before modifying the electronics of this guitar.

Thanks.

Would depend what the traces are on the PCB. You'd have to work it out.

You can also just get a standard toggle (in place of the 4PDT) and wire it up - that would be much simpler.

Thanks for the speedy reply!

Yeah, you're right about it being simpler in the long run. I think I'll do that.

You mentioned a standard toggle. Will this Dimarzio switch fit the JP6 correctly? DiMarzio EP1108 DPDT On/On/On 3-Postition Mini Switch | Reverb

(I tried finding the hole size and height for the JP6 switch but came up blank)

You'll only have to unsolder the green and red wire of the neck pickup and the white and black of the bridge pickup, those are the wires that get switched to ground, and split the pickups.
If you remove them from the switch, the Pickups are always full humbuckers
You'll just have to solder the Green&Red and the White&Black wires together and put some Heatshrink on the end

Here you go. This is the mod I did and there is some supporting diagrams from the forum in there too.

You can also install a jumper between #4 & #5 and a second jumper between #2 & #3. This will force the middle position to be full humbuckers.

Expanding on this, these are the pads you would if you want to install a push-pull pot to have a choice of split coils or full humbuckers.

Is it possible to do the same push/pull mod on a Sterling JP60?
what is the effect on the others positions of the toggle switch? do the humbuckers stay in series or are coli-split?

thank you

You can install a push/pull pot on the Sterling JP60 to split the humbucker coils - it will be split in all 3 positions

Hi...i am a new user here. As per my knowledge the white and black of the bridge pickup, those are the wires that get switched to ground, and split the pickups.If you remove them from the switch, the Pickups are always full humbuckers.

What gauge wire do I use?

This seems like the simplest solution, I will try this tonight unless someone has a better idea. I am playing on Sunday so little room for error if this goes south....

You would need to solder the black and white together. Simply removing them will leave the pickup coils as an "open" circuit.

I generally use 22awg solid copper wire for the jumpers between pads 2/3 and 4/5. I flux and tin the wire (and pads on board) prior to cutting the jumpers to appx 1" length. I then bend them into a U shape, poke them through the holes, and solder them in place. The final step is to cut off the excess jumper wire sticking out the back of the board. If you ever want to go back to the split middle position you can simply cut the jumper wires.
