Urgent help with Strat wiring. Antiquity Texas Hots and SH-4 JB.

[Damn Deal Done]

Hello all. This is my first post.

Please help. I am slowly going mad trying to find reliable and easy to follow information on how to wire up my particular setup. I can not find instruction for the SH-4 to tell me what the wires are. Or even a simple diagram on coil splitting it on a Strat with a bridge tone control.

I will give you the details of my desired setup.

*********************************************
Neck = Seymour Duncan Antiquity Texas Hot
Middle = Seymour Duncan Antiquity Texas Hot RWRP
Bridge = Seymour Duncan SH-4 JB Fullsize Humbucker

250k Volume
250k Tone .022 Cap (For Neck and Middle)
250k Tone with SPST push pull switch .022 Cap (For Bridge and Coil Split JB to Slugs).

Standard CRL 5 Way Switch. Standard N,N/M,M,M/B,B configuration.
*********************************************

All the components are installed and ready to be soldered. I have chosen to go with separate Caps for the tone controls because I might experiment with different values on them.

I would like Tone 1 to control Neck and Middle, and Tone 2 to control just the Bridge. Tone 2 should split to single coil when pulled up. Coil split to the inner slugs.

Can someone please help me with a wiring diagram and an explanation of what the wires coming from the JB actually are? Will the JB be out of phase with the Antiquities?

Below are two diagrams.

My original Strat Special wiring. This is the original wiring in my strat that I am replacing. Stacked tone control and separate switch for the coil split. Look like a resistor to lower the value of the bottom tone pot.



This is the new electronics. CTS push pull pot replacing the switch and a standard CTS tone pot replacing the stacked tone pot. Can someone please help wit hthis wiring?



Many thanks

Re: Urgent help with Strat wiring. Antiquity Texas Hots and SH-4 JB.

Search for the duncan wiring colour codes. That will give you what the colours do even if it doesn't some with a small diagram in the box.

A stock start wiring scheme will give you most of what you want, with a couple of mods. Given you have the same cap for both tone controls they can share as the vintage strats did too. The push-pull is a separate switching, and the coil split is often shown on a vol pot. The important part is the wires on the 6 lugs of the switch......how the pot below is wired is not important.

Hello

I found the info on JB

Black = North Start (Hot)
White = North Finish (Link)
Red = South Finish (Link)
Green = South Start (Ground)
Bare = Always Ground

To make compatible with certain pickups, make Black ground and Green hot. I think.

I drew my wiring diagram.

I do not know if the coil splitting part is correct as I just guessed that part based on the old wiring. But think the tone controls are correct.

Can someone please take a look and give me some pointers/corrections. Especially the push pull splitting part. I don't want to share tone caps because I want to experiment with different values.



Thanks

Re: Urgent help with Strat wiring. Antiquity Texas Hots and SH-4 JB.

A push/pull switch on a pot is not a SPST, it's a DPDT on/on switch.

Your color coding for the JB is correct. You do not want to change the ground and hot connections since all of your pups are Seymour Duncan and the middle pup is already RWRP... so green is ground and black is hot.

Your diagram doesn't show any connection of the neck and middle pups to the switch. Your p/p (if it is a SPST, which I've never seen) is splitting to the screw coil not the slug coil.

Here's a general diagram:

Here's how to wire the split if you want to switch to either the slug or screw coil:

With the JB I find that wiring it to switch from series to parallel is a much better way to go than splitting it:

The Texas Hots are wired out of phase with the regular Duncan line, though, so keep that in mind if there are phase issues.

Oh, I didn't realize that. I guess they did that to get along with Fender pups, since these would usually be used in a Strat?

Hello.

Thanks for the tips. I clicked with it and managed to understand what is going on with guitar circuits. Was stressful but I am glad I have progressed into this area.

Finished circuit.



My first soldering job.

It is very noisy so will have to check the shielding again. But the pickups sound amazing. The tone controls are really usable. The whole thing sounds punchy. The Texas Hots are a little on the low output side for my liking and the output difference between them and the JB is a bit too extreme. But I might be able to balance this a bit better with adjusting the heights.

Does anyone know from this updated diagram if I am splitting to the slugs or screws?

The JB is in phase with the Texas Hots in this circuit, but it was out in my old circuit.

Thanks

Re: Urgent help with Strat wiring. Antiquity Texas Hots and SH-4 JB.

With your latest diagram you are splitting to the slug. Do you get hum cancelling with a split JB combined with the middle? (If not you can simply swap neck and middle pickups position)

The JB is going to be much hotter than the Texas Hots. Unfortunately that's the compromise having beautiful vintage Strat neck and mid tone and fire breathing hot rodded humbucker bridge tone. Pickup height can help to balance, but I like switching to the bridge and have it really push the signal, then go to the neck for more delicate tone.

Yes still getting hum cancelling. Positions 2 and 4 are to die for. Just want to deal with the noise a bit better, my shielding must be fudged somewhere. Will post a gut shot later tonight.

Re: Urgent help with Strat wiring. Antiquity Texas Hots and SH-4 JB.

My first ever soldering job. I replaced everything in this guitar. All new pickups, pots, switches and wiring. Painted two coats of thick shielding paint in cavity. Managed to make a neat job considering.

The JB wires were cut really short by previous owner. I might have made a better job of the routing if I had a bit more to work with. I still suck at soldering to the back of pots, but as you can see, everything is shiny.

Not bad for a first try.

8 wires to the back of the volume pot. That seems excessive.

I do not have a continuity tester to test the grounding so I do not know if the noise is just normal or because of faulty ground. Just seems noisier than the previous pickups and electronics.

Suggestions and opinions welcome.

Cheers

Re: Urgent help with Strat wiring. Antiquity Texas Hots and SH-4 JB.

You say you are getting hum cancelling in positions #2 and 4. Position #1 is the JB (humbucker) so I assume you are getting hum cancelling in that position. So are you only getting hum from the single coils? That's normal.

Nice wiring job with a bit of overkill. Your soldering could improve, but that will come with more experience...perhaps you could use a more powerful (hotter/higher wattage) iron. 50 watts is ideal. It helps to have a chisel tip rather than a point, for soldering pots. It transfers more heat quicker.

With a shielded pickguard, the ground wires between pots is redundant.

You might want to use your shielding paint to fill in those bare marks on the body (unless that is copper tape that I see...I can't tell for sure from the photos).

Otherwise, I don't see anything wrong with your wiring.

Re: Urgent help with Strat wiring. Antiquity Texas Hots and SH-4 JB.

Yes I am getting hum cancelling in 2 and 4. But notice no difference when I touch the strings in any position. Before I did these upgrades, there was a definite decrease of buzz when I touched the strings. Now nothing changes.

Using a Hakko FX888D set to 400c. But my tip only has a small flat spot at the end. Perfect for lugs, but I really struggled with the back of pots.

Yes, that is copper tape. A few strips under the paint to connect to the scratch plate.

Cheers

Yeah, weird, huh? It throws a wrench in the works when people combine them with other SD pickups, though. They are (I think) the only SD pickups wired like that.
