Ok to combined Stack pickups without splitting?

[txbdan]

I'm wiring up my HSS build with a JB in the bridge and two STK-S6 in the middle and neck. I was planning on using the toneshaper kit and diagram shown here:

ToneShaper Wiring Kit, Stratocaster, Auto-Split (HSS2)

Our wiring kits for Stratocasters have everything you need to complete the job the right way! Great parts, great documentation. Best on the market!

toneshapers.com

It assumes standard single coil neck and middle pickups.

I was also looking at the Seymour Duncan wiring diagram that came with the STK-S6 pickups and it splits these in the 2 and 4 combined positions. I this necessary or "better" enough to try and merge these two concepts together? The SD concept would work, the main difference I think is just that the Toneshaper diagram switches in a parallel 470k resistor when on the single coils so the 500k volume works like a 250k and I think it also assigns the tone knobs differently making Tone 2 dedicated to the humbucker.

I wish these diagrams had an actual schematic. Trying to figure these circuits out is baffling. And I'm a EE. ha

Edit: this diagram might work if I could merge it with the toneshapers' tricks

you dont need to split, there is a slight difference in tone, but not enough for me to worry about

Actually, would this work? I added the red wires form the STKs to the pole of the switch that grounds things. I put them on position 4 and jumped to 2 so that all the pickups get split in those positions.

Do I need to reverse polarity on the middle pickup? The Seymour Duncan documentation doesn't show that

Sorry, I forgot to hit post on that reply, I see you posted first. Ok I'll wire without splitting for now and see how it goes. Thanks

Ah. A man who speaks my language. Here it is in good ole fashioned schematic format:

It’s like a breath of fresh air. Nice work!

I got my guitar all wired up using the ToneShapers diagram above but without my attempts at splitting the STK-s6s as that wouldn't work. So only the JB gets coil split in position 2. I'm not using the big tan resistor since the split JB should have plenty of output.

There is definitely no hum in positions 5, 4, and 3. There is some position 2 and even 1 which is pure JB. Is it expected in position 2 since the middle pickup is not split and the JB is split? I measured the resistance at the output jack of all positions and they seem to be wired right.

I also notice the volume knob falls off pretty quick and is basically off at position 5.

I'm not immediately in love with the STK-S6s, but they're growing on me. They sound bright enough, but almost a little thin and characterless, like a PA or something. Kind of HiFi. Still playing with pickup heights and stuff.

Yeah, if any position has an odd number of coils, you will still get hum. Even a position with an even number of coils, but they aren't matched, you will still get hum.
