Hi!

I'm thinking of doing this:

http://www.seymourduncan.com/support/schematics/phase_switch_coil_split_hb.html

on my Squier Esprit which has Duncan-Designed humbuckers... '59-style neck pup with 7.3k dc resistance, and JB-style bridge with 16.6k dc...

From the SD wiring diagram, it seems to me that:

1) I can hook up the red&white wires from both pickups to just 1 push-pull pot for coil-tapping. (one r&w pair to each middle lug)

2) I can also wire the push-pull to have just one common connection to ground.

3) With the bridge pup being 16.6k, I may possibly pull off the coil-tapping with just a 250k push-pull pot (as that's what I have left w/o ordering from overseas) instead of 500k (w/c I'm reserving as the OOP switch), without the tone control suffering too much.

I would appreciate your comments, guys. Many thanks!

Yes, you can split both pickups like that. Imagine the DPDT push-pull like this:

1 4
2 5
3 6

Connect 1 and 4 to ground (you can connect them to each other and use only one wire). Connect 2 to red and white from one pickup, and 5 to red and white from the other pickup.

250k vs 500k will have no effect on the switch. If you find that the tone is too dark when you have it all the way up, use a 500k push-pull instead.

Many thanks for the confirmation, ratherdashing! That's exactly what I thought too. But, being a newbie at wiring, I just needed your inputs.

It'll take me a few months to get in a 500k push-pull. In the meantime maybe I can make do without a tone cap on the 250k push-pull pot.

last question: what happens when you throw both OOP and coil-tap switches? Will I get the expected result of a single-coil, out-of-phase sound, or is there a possibility of throwing the circuitry out of whack, or even have it go dead? In which case, I will not push thru with the mods.
