all the info above about pups is absolutely correct ...
i'll add my 2 cents about the switch itself (if it is an "8 lugs in a row" switch) ... you can verify this info with an ohm meter to test continuity
O A3
O A2
O A1
O A0
O B0
O B1
O B2
O B3
with the 5-way switch:
in position 1, A3 gets connected to A0 and B3 gets connected to B0
in position 2, A3 + A2 get connected to A0, and B3 + B2 get connected to B0
in position 3, A2 gets connected to A0, and B2 gets connected to B0
in position 4, A1 + A2 get connected to A0 and B1 + B2 get connected to B0
in position 5, A1 gets connected to A0 and B1 gets connected to B0
hope this helps
what are you planning for the 5 positions for your H-H guitar? are you using mini toggles or push/pull pots to do coil splitting?
