'59 2 core and Custom 5 4 Core Custom Wiring

[mr2jay77]

Afternoon Guys,

Performing my first upgrade on a guitar at the moment and I've hit a brick wall with my wiring. A bit of a background. I have an ESP Ltd EC-256 which I love to play. Down side is the stock pickups are pants. Best solution was to upgrade all the electrics hopefully making a decent sounding guitar. All being well, I may consider an upgrade to my Gibson SG at some point but I thought I would give a go on a cheaper guitar to begin with.

So, the selection I made was a Seymour Duncan '59 in the neck and a Seymour Duncan Custom 5 in the Bridge. These are running through separate volume pots (CTS) with a shared CTS push/pull tone pot. The '59 is a 2-core pickup,wheras the Custom 5 is a 4 core.

I've downloaded the Seymour Duncan wiring diagram for 2 Humbuckers, 2 Volumes, 1 Push/Pull Tone (Split) with a 3 way toggle but the site doesn't give the option of 2 or 4 core wiring

What I am trying to do is run the tone push/pull as a coil split on the custom 5 while retaining the tone function on the '59. How would I wire this up? Please help, I'm in over my head and confusing myself further at this point and literally have the pickups to solder into the pots left to do.

Thanks

The center conductor "core" of the 59 goes to the outer lug of the neck volume control, the braid solders to the back of the control. The center lug goes to the toggle switch.

The black wire of the Custom 5 goes to the outer lug of the bridge volume control, the green and bare wires go to the back of the control. The center lug goes to the toggle switch. The red and white wires go to the push pull switch.

The output of the toggle switch goes to the jack and the tone control.

I can get you a drawing in a little while.

The cap says .047. I'd use a .022, or just leave whatever is in there.



Personally, I'd see whether I liked it better to have the switch toggle between series/parallel mode instead of series/split...

Thanks, that's perfect

I wired it up similar to this last night and although the '59 is singing like an angel, I've got big problems when I switch the Custom 5 in. I'm 95% convinced that it is an error I've made with the wiring so I'm going to open it up again tonight and look for issues.

I'm not 100% sure on the Push/Pull connections on the CTS pot. At the moment I have the red and white wire connected to the C1 pin and the ground going between the "1" pin and the case. Should these be the other way round or doesn't it really matter?

If the red/white pair are connected to ground with the switch one way, and floating the other way, then there should be no problem with that portion on the circuit.

Double check that the black wire goes to the outer lug of the volume control and the green and bare are both connected to ground.

Then it must be an error I have made.

I've looked at a photo I have taken and although it isn't tidy, it seems to follow the right rules. All I can think of is it is accidentally grounding somewhere it shouldn't. I won't know until I'm back with the guitar and open it up again.

Thanks for your help so far :bigthumb:

OK, an update. There seems to be an issue with the wiring to the volume pot on the Bridge pickup. I THINK it's the ground so I'm going to strip them back and rewire them to make some cleaner solders.

I've already stripped back and tidied up the red/white pair (I'd caught the wire further back with the soldering iron and hadn't realised)

I'll sort out the soldering and post up some pics

Thanks for your help so far
