Someone will (and has) come along when they have the (free) time.
This one in particular, but I'm hoping to modify it by using a 5-way Super Switch instead. I'd like to have the standard Strat combinations, and then with the switch toggled, to have Neck & Middle in series (as shown), Middle & Bridge in series (as shown), but rather than using the slightly out-of-phase combinations and leaving a position unused, I'd like to add Neck & Bridge in parallel, Neck & Bridge in series, as well as all 3 in series.
This is A Mike Richardson design. There are others that may already do most of what you want.
