Jimmy Page Wiring - Again...

Hi all, long time reader first time poster. I've seen a lot of posts on the JP wiring, but none outlining the issues I have...

Recently I finished a Kit LP style guitar. I replaced most of the junk hardware, spent a lot of time making everything fit properly (body was protruding from bindings, neck didn't fit right) and wound up with a surprisingly playable guitar that has a bucketload of sustain - definitely better than I was expecting.

Initially I wired it up with standard "modern" style wiring with the standard Jazz pup in the neck & JB in the bridge.

I got bored with this wiring after about 15 minutes, so threw in a pair of push/pull pots - Bridge splitter in the bridge tone position and phase switch in the neck tone position. This was my first time wiring up push/pull pots and I loved the results - especially the out of phase voicing - but still wanted that little bit extra. I picked up another 2 push/pulls and set to task wiring up according to the the Jimmy Page diagram that Seymour Duncan have in their files.

First up I found buzzing issues as there was no good earth, so I earthed the pots together - problem 1 solved.

Next problem is this - the bridge pickup does not work when the pots are all in the down position. When I pull up the neck tone pot (series/parallel) it seems to work. I checked and double checked my wiring but couldn't see a fault in it so in frustration I pulled it apart and tried a different setup which seemed to work, but had issues with some settings running at half volume, so again I pulled it apart.

I eventually found a tutorial which walked me through the SD setup once more, but alas, when it was finished I had the same issues with the bridge pickup outlined above.

Does this sound familiar? Does anyone else have these issues? Is this maybe how it's meant to work? I was initially thinking I could have a dead pickup, however the phase switching works and in the first incarnations of standard and "custom" wiring the bridge pickup had no problems either in standard, split or out of phase modes.

If anyone could help me I would be most appreciative.

I'm working on a JP wiring rig right now, but you are ahead of me. Also, I'm doing the full JP wiring with the switches on the pickguard, not the simpler Seymour version.

To get my wiring skills back in shape, I just threw some Seths in my Les Paul Studio using 50s wiring, and I had the half volume thing you are describing. For me it turned out to be cold solder joints. I just reflowed the solder and it was fixed.

SD's diagrams don't say which is up or down on their push pulls. I've had to read the wires very carefully to make sure the orientation does what I think. That bridge hot wire as a long path to the output. If you one-by-one pull up on the knobs, is there a moment where it comes on? I would start from that knob and work my way back to the bridge pu.

Yes - when I pull the Neck Tone (series switch) up it works BUT it sounds like it's in series - there is no discernible change in tone when I flick the 3 way up to bridge. This is the opposite of what I'd expect so I'm wondering if the switch is backwards in relation to the diagram? The other switches, all the same brand (DiMarzio) all work in the layout provided though so I'm at a bit of a loss as to why that would be if it is the case.

I'll try reversing the switch and see if that helps. If not I'll go back to the second layout I tried, knowing it works, but sharpen my soldering iron first to avoid any cool spots in the tip. By the time I finished last night I realised there was a massive divot in the side of the tip and it was getting near impossible to solder anything that was hard to reach so the volume issues could well have been down to dodgy soldering.

Best of luck with the pickguard switch setup! I thought of doing the same but don't want a pickguird on the guitar - I spent a lot of time getting the finish where I want it and would like to show as much of it off as I can!

Neck tone up puts them in series, so that sounds right. Based on the description, I think the blue solder connections might be the next thing to check. Those are the points that carry the bridge hot signal alone. (Sorry, I missed one - the center lug on the bridge volume. Check that one also.)

Re: Jimmy Page Wiring - Again...

Thanks everyone for the responses.

When I got home from work tonight I had more of a chance to muck around with the guitar. It turns out that buth volume pots (splits) are wired right, but the two tone pots are wired backwards.

With both push/pulls pushed in, I get in series and out of phase. When they're both out I can play both pups as per normal. Not an urgent issue so I'll fix it when I get to it.

I know what the fix is though - don't wire up a guitar at 11:30 at night!

Once more, this is not the right JP wiring mod. The right one was posted by ArtieToo and, it's in The Vault.
I've got my own diagram here: http://hermeticoguitar.blogspot.com.es/2012/11/wiring-diagram-jimmy-pages-mod.html

But, since JP wiring is sorta weird (because presents a lot of blackout positions and it's difficult to mentally map), I would recommend you my own take (more logical and adds one more combo to the JP wiring):

Re: Jimmy Page Wiring - Again...

I left a comment on your YouTube video for this last night, Hermetico. I saw your diagram last night and I reckon I'll run with it. I did use the "right" wiring you mentioned but got half volume on a lot of settings.

I plan to use your version though, it seems to make more sense I just hope I can keep track of which bar of the humbuckers is active when I split them.
