I've never installed a pick-up before and the wiring diagram is missing (SHPR-1)

Hello everyone,

About 6 months ago a friend of mine talked me into fixing up one of my older guitars that I hadn't been playing (ibanez gax70). One of the pickups had died long ago and I decided to replace it with the SHPR-1. My friend said he'd do it for me, so I gave him the guitar and the pickup when it arrived and left him to it.

Fast forward to now. Just got my guitar. He at least took the strings off, removed the dead pickup, and mounted the new one in it's place. But I'm going to do the wiring, or I would've never seen my guitar again!

I've never put in a new pickup on a guitar before, but I'm good at soldering (I make my own pedals (byoc)) and it seems pretty easy if I had the right wiring diagram.

It has the stock pickup in the neck position still and the SHPR-1 in the bridge. Currently there is a 3-way switch and 4 pots (2 volume, 2 tone). The way that made sense to me was to add another 3-way switch to choose between humbucker, p90, and single coil and use the existing 3-way for pickup selection.

I just don't know which wire goes where.

If someone could please give me some advice I'd be eternally gratefull.

Thanks!

jonnn

Slight change of equipment. For some reason he replaced one of the pots with a push/pull pot (I've never used these before).

idsnowdog - the 3-way switch I currently have is whatever the 3-way toggle switch is in your diagram. And thanks for your quick reply!

Unfortunately, I don't think that first diagram is going to work anymore for me, unless I go back and get the right pot. Plus I have four pots on the guitar, not two.

Well with an on/off/on you would have humbucker or one of the two coils with the middle off. The number of pots and number of pickups is largely immaterial. When the four wires go into the switch only two wires come out positive and negative. The negative goes to the back of the volume pot, while the positive goes to the 3-way switch or the hot lug on the pot. So you're only changing two points after the on/off/on switch. My guess is the push/pull pot is used for coil splitting.

OK. Well I can go pick up an on-on-on switch. And I certainly don't mind drilling new holes in this thing. Should I get another 500k pot to replace the push/pull? Or is there some reason to keep the thing?

Hopefully Heremetico or Artie will read this thread and look over the wiring diagram to see if the on/on/on will do split in two positions and full humbucker in the other. The push/pull was probably used for coil splitting and could be replaced.

OK, thanks again for your help. I'll head to the store for the switch and pot tomorrow. I'll keep checking in to see if anyone has anything to add though.

Yes. Combining the Ibanez diagram with the DP3T on/off/on element from the SD schematic will do what you require.

NOTE: For your proposed circuit, the push-pull pot that your friend installed is redundant.

If space in the GAX control cavity is tight, consider mounting the P-Rails using a Triple Shot surround.

+1 on triple shot
 
Re: I've never installed a pick-up before and the wiring diagram is missing (SHPR-1)

Just thought. There are a few things that the push-pull pot could do.

1) Phase reversal of the black and white output cables from a Triple Shot.
2) Coil tap of the neck PU.

If you look at the schematic posted by ehdwuld, you should notice a third, unused, insulated output wire on the humbucker cable. This is the series link / coil tapping wire. :naughty:

Dear John dude,

first and foresmost, and without reading anything else in this thread, i have to ask, do you own the proper soldering iron and solder? do you feel confident enough?
 
Re: I've never installed a pick-up before and the wiring diagram is missing (SHPR-1)

Thanks for the info funkfingers! And thanks for confirming the wiring diagram. I'll check out the triple shot. And I think I'll keep the push/pull for one of your options you posted as well. I understand the phase reversal one, but not the coil tap. Does that give me the ability to just use one coil from the neck pickup?

And astrozombie, I own a soldering iron and I'm confident enough. I think I might need a different kind of solder though, the kind I have I've been using for circuit boards.
 
Re: I've never installed a pick-up before and the wiring diagram is missing (SHPR-1)

hey you could use the push pull pot to try out different caps

use it for a tone control
down is one cap up is another

make one dark guitar and one bright one

not alot brighter but ya know
 
Re: I've never installed a pick-up before and the wiring diagram is missing (SHPR-1)

Not a bad idea ehdwuld, but right now I'm leaning towards the coil tap idea, assuming it means what I think it means.

The Triple Shot is awesome! I think I'll be ordering one of those. What's the difference between the TS-1 and TS-2? I'm sick right now so I'm a little out of it and likely missed the obvious differences.

Thanks again for all the help! Wouldn't be able to do it without you!
 
Re: I've never installed a pick-up before and the wiring diagram is missing (SHPR-1)

Figured it out. I need the ts-1.
 
Re: I've never installed a pick-up before and the wiring diagram is missing (SHPR-1)

ok, I'm resurrecting my months old post. I finally got my triple shots and have installed one on my p rail. I'm keeping the stock neck PU, can I install my other triple shot on this? As the diagram a few posts up shows, these pickups only have red, white and black. How would I go about this? Thanks so much for your help!
 
Re: I've never installed a pick-up before and the wiring diagram is missing (SHPR-1)

My mistake. It's just one red casing that has a white wire and what would be the ground. I'm guessing I can't use this with a triple shot?
 
Re: I've never installed a pick-up before and the wiring diagram is missing (SHPR-1)

To use your stock Ibanez neck PU with a Triple Shot surround would require conversion from the original Ibanez output cable to four conductor + shield cable. Perhaps, you have some left over from the P-Rail/Triple Shot installation?

IMO, making this alteration is fiddly and not for the inexperienced. Apart from anything else, I suspect that the Ibanez neck HB will sound weedy in anything other than regular series wiring mode.
