I'm in the middle of planning my circuit for my SC1. It's using two, four-wire humbuckers.
Option 1;
4 Push pulls to turn each coil on/off
1 vol and 1 tone per humbucker
Kill switch
Empty hole for I don't know what (phase/series/parallel?, master tone, built in overdirve/distoriton)
Option 2;
4 push pulls for vol/tone on each coil
Kill switch
Phase/series/parallel
