Question for the masters about Page wiring diagram...

[1999nbmZ]

I'm currently awaiting my new pickups, and I'm trying to get the four push-pulls wired up ahead of time. I've been using these two diagrams for reference, and I've noticed that they are different.

I believe the pots are wired the same, but the part that has me confused is the selector switch. Now, both of these say they are SD diagrams, but I have a feeling the second one is the legit diagram.

Look at the two center prongs on the selector switch. The first diagram has these prongs soldered together, and then feeding the output. The second keeps these points seperated, and connects them through the neck tone push-pull.

Any idea on which one is correct, or do they both serve the same purpose? Any help is appreciated.

Re: Question for the masters about Page wiring diagram...

The second drawing is a bit of a collaboration. I did the drawing, but borrowed several bits of artwork from Seymour Duncan in order to make it more Duncan-esque. (The pickups, bridge, neck and strings, are from SD. The push-pull pots and wiring are from me.) The drawing is an exact copy, (electrically speaking), of an official Gibson diagram, supplied by forum admin Robert S.

I believe the second one is the "official" one, assuming that Gibson Inc. is the "authority". I can't say for sure on that one.

Btw - welcome to the forum.

Thanks for the welcome, and A+ on helping quickly!!!

Have you ever wired this system up yourself? I've seen so many versions of this diagram that I'm starting to wonder if these are all just different people's interpretations. Do you know where I can find the Gibson schematic? I think I even saw you post that Gibson's schematic wasn't correct.

Thanks again for the help, I'll post up pics and possibly some sound clips once I'm done.

Artie is AWESOME!!!

Re: Question for the masters about Page wiring diagram...

I haven't personally, simply because it doesn't really interest me. Other than from a technical point of view. I'm not really crazy about push-pull pots in operation. But I know that Robert S has, and I believe he loves it. I'll see if I can find my old copy of the original. It didn't have "mistakes" per se. They were more like "typos" and omissions. You could see where a wire was supposed to go, just the ink wasn't there.

Let me see if I can 'round it up.

Here's the original that I got from Robert. Unfortunately, I'd already touched up the missing lines, so you can't see the "typos":

Re: Question for the masters about Page wiring diagram...

Now, that looks like the pic in the second link I posted, but much easier to read. I've seen this one as well, and the only thing that confuses me on this one, is the caps have changed values down to .02uf Should I stick with the .046's? (.047's are what I got.)

You're on fire Artie, I can't tell you how much this has helped...

 

[Artie]

Re: Question for the masters about Page wiring diagram...

The caps aren't really relevant to the JP wiring per se. Just use whatever value you like best. I prefer .022uf's for my tone controls. Just depends on the pups, the guitar, and your rig.

Re: Question for the masters about Page wiring diagram...

Sounds good, I actually ordered both so that I could play with the sounds. I was just trying to figure out which one to start with.

Thanks again.

One other question, your diagram here shows a three conductor pickup. Mine is a four. Is the fourth wire just for a ground circuit, or does the lead hooked to the red/white wire actually come out of the harness separated?

Do you know where to find pics of the control cavity of a guitar that already has this set up? The only one that I found I think you were using as an example of a bad wiring job.

Sometimes I sleep.

Their just showing red and white as one line. I do that sometimes also, just to make it easier. Treat it as one wire, but remember its two. Just route them to the same place.

Unfortunately, I don't. There's enough folks here who've done this wiring that hopefully, someone might be able to post one.

Nah . . . I think I'll have a beer.

Re: Question for the masters about Page wiring diagram...

Well, I got mine together. I tried to keep it neat, but there are a ton of wires in this circuit! I would never consider this to be "serviceable". If I need to change caps, the whole assembly is coming out as one piece.

Thanks for the help Artie, I'm still waiting for a new bridge, but I have faith this will sound like a champ...

Re: Question for the masters about Page wiring diagram...

Nice job. That actually looks pretty neat compared to some I've seen.

Re: Question for the masters about Page wiring diagram...

Nice, looks way cleaner than mine. It's much easier to wire up the whole assembly as a unit then drop it in. Unfortunately my PU leads are a little long and just jammed in there.

What pickups and caps did you end up with? What's your opinion on the JP wiring? I think I'll automatically put it in any LP style guitars I ever get, I love how you're all stock with them down, but can get some cool alternative tones with a few pulls.

Re: Question for the masters about Page wiring diagram...

Nice job, as stated above, that cavity also looks much neater than mine as well.

+1 PFDarkside, I'm gonna use JP wiring all the LPs I own in the future also.

Re: Question for the masters about Page wiring diagram...

I tell you what though, I am not looking forward to doing this again. My next guitar may just run straight 50's wiring.

By the way, I installed the .47uf caps per the diagram posted above, and I'm wondering what would change if I dropped in the .22uf caps. Any opinions, post 'em up!

Re: Question for the masters about Page wiring diagram...

Hey there Artie, one more question for you.

I'm getting a good amount of static every time I take my hands off of the strings, and I'm not sure where that's coming from. This also goes away if I touch the casing on the guitar cable. I have 0 ohms between the bridge and the output jack ground, and I've verified ground to all pins that are labelled as needing ground.

The only thing I have seen on other guitars that I didn't do on mine, was ground the cases for the pots. Would this cause the problem I'm having? I'm not sure how that would make a difference due to the fact I am just increasing the resistance between the pickups and the volume pots.

Any ideas?

Re: Question for the masters about Page wiring diagram...

im pretty sure you should ground the cases of the pots.

 

[1999nbmZ]

Re: Question for the masters about Page wiring diagram...

Well, I ran a ground circuit for all of the pots last night, but I am using the ground lug on the output jack for my common ground. All grounds run down to the output jack. Is that not the correct way to do it?

I have noticed that with the guitar unplugged, I still get the same static (when plugged in it is less noticdable now that I've grounded the pots). However, if I plug in the guitar with both volumes rolled off, there is no static. It comes back when I start bringing the volume pots up.

I did measure .4 ohms resistance between the plug housing plugged into the amp, and the bridge. Is that enough to cause my problems?

On a side note, I also swapped my .22uf caps in instead of the .47uf caps that I was running. This thing sounds much better to my ears now. It sounded good before, but too dark for my taste. The tone was still dark when I was running in coil tap, and now it seems to sound "right" to me in all configurations.
