Hi Everyone! I'm brand new to guitar wiring in general, so i need a little help. I have just bought a Cort Aero 11 guitar (push and pull switch); also bought 3 seymour duncan pickups: Custom Humbucker (bridge) -single coil(middle) and Hotrails (neck). In the duncan's site i found some wiring schemes, but i could'nt find this set up. These are i found:
A hotrail pickup is just a HB squeezed into a single-coil size. Just like a HB, it has 2 coils and 4 wires (plus, usually, a bare wire for grounding the frame of the pup). The 4 colored wires are what's important, and they'll be the same on the HBs as on the hotrails (so long as we're talking all SD-brand pickups, which we are.)
So your hotrail gets wired just like a HB, and vice versa. You can use either one of the above diagrams with your pickups, as is, no changes required.
The only difference between the 2 diagrams is that, in the first one, only the bridge HB is split, and in the second diagram, the P/P splits both the neck and bridge HBs simultaneously to single coil operation. So, do you want to split both HBs, or just one?
If you want to split just one, the bridge pup makes the most sense to split, so that one has a single-coil treble-ish sound for lead work. Also note that, on that first diagram, SD seems to assume that only the bridge HB is an SD pickup, as the wire colors aren't the same for the neck and the bridge HBs. If all your pickups are SDs (as you indicated) then the green should be the ground for both HBs. The neck HB in that diagram also seems to be a 2-wire (plus the bare shiled) type, rather than a 4-wire HB.
If you want to split both the neck and bridge HBs, then the second diagram will do that. But, be aware that splitting the hotrail may not give you very much output, since the remaining coil is so tiny. This can result in a big volume mismatch when combined with the middle in single-coil mode.
Hi newey! Thanks a lot for sharing your knowledge. I've been playing guitar for a long time, but rightnow i'd like to explore new wiring to find new sounds. I'd like to know if there's any way to keep the humbucking function for my bridge pickup, and the same time have the possibility to split it using the push / pull switch? This is because i play metal sometimes, and i like the sound of that pickup in the bridge. Do you have any advice for me?
Well, the first diagram you posted keeps the bridge HB when the P/P is down, and splits the bridge to one coil when pulled up. You will, of course, lose the hum-cancellation with just the single coil operating, as it takes two coils to tango, or to make a humbucker. You will want to arrange things such that, when the split coil bridge pickup is combined with the middle single-coil, the two are humbucking in combination. This can be done, but you will likely need to do some testing to determine which coil should be the split one from the bridge. However, since they're all SD pickups, if SD's literature tells you the magnetic polarity of the SC middle (i.e., North vs. South), then we can work out which coil to split with that information.
