Hello... I am having a hell of a time getting this mod going. I have searched for diagrams and have followed the thread that had detailed pictures but I still cant get it right. I have an old JP6 with out the peizo pickup. I installed the push pull pot but..with the pot down I get bridge, The two inner coils and neck.. With it pulled I get bridge(inner coil) the two inner coils, and neck inner coil. What am I doing wrong.. I can not get the two full humbuckers going at the same time with the pot pushed and the 3 way in the center position. The center position for the pot pulled or pushed is the same.. the two inner coils.. Please help ...a diagram would be great as well... Thanks in advance!!

Continuing to mess with it... The middle position sounds like a clean channel while the others have gain. Its like the power is cut in half. I am using an all parts 500 k push pull knob not a dimarzio ..That shouldn't be a problem .should it?

Not sure which diagram you followed, but that's what a lot of people wanted- split HBs in the center position, with the push/pull up or down. So you may have wired it up correctly.

I would contact MM customer service on Monday and ask them for the JP schematic with the push/pull, and start from there.

Btw, no, it shouldn't matter what kind of push/pull you're using.

Make sure that the bottom lugs are grounded.

Here is the stock BFR wiring with a push/pull.

In the mod thread, he's doing it just a little different, and I've done this too, it sounds great! I'll point out the differences zoomed in at the switch, verse what EBMM wiring diagram shows above.

The angle of that pic is hard to tell your current wiring, especially at the push/pull switch. If you take some multiple angle shots, maybe we can help a little further.

First off I would like to say ...Thanks a million for all you guys help. I took pics of the connections... I hope they are ok.. As far as the coils.. I originally wanted the pushed (full bridge, Full Both Full Neck) and pulled (Single inner coil, Middle inner coils, and neck inner coil). But in your diagram Pete you show that I could also have an option to have pushed (full bridge, inner coils, full neck) and pulled ( single inner coil, middle humbuckers full and neck inner coil. Is that correct.. That sounds interesting in that is sounds like it would be a little more versatile due to the more drastic tone changes. I am open to all suggestions... I play in a classic rock/Heavy Metal cover band and also write my own stuff so I like versatility. Thanks again! 091.JPG 093.JPG 094.JPG 095.JPG View attachment 21753

No problem, I hope we can help! I do see where there is confusion, the sounds you are looking for are not in those diagrams. My diagram shows how to change the middle position to full humbuckers when using the original EBMM JP toggle.

The standard JP wiring is
Bridge, Inside coils, Neck

The BFR JP wiring incorporates a push/pull pot.
Bridge, Inside coils, Neck
Bridge, BOTH, Neck

(There are 2 versions of this which I show in my diagram, depending on whether you want the split coil center position on the push or pull side)


If you want to wire your JP as you mentioned then it would probably be easier to start from scratch and ignore my diagram.
Bridge, BOTH , Neck
Bridge inner coil, BOTH inner coils, Neck inner coil

There are a TON of diagrams on the DiMarzio website ---- Wiring Diagrams | DiMarzio

It looks right going by the photos. I cannot see, but assume that the neck red in on the (red) PCB. What also doesn't show because it's taped, is that both neck and bridge are joined, such as the bridge should have both red and green together, then extended to reach the push/pull lug (left side-middle).
The neck should have the white/black joined together, and extended to reach the push/pull lug (right side-middle). What isn't quite working when you mention that there might be a grounding issue? no sound, noise, not actually splitting coils, etc?
