Can an Ibanez five way be used as a 3 way or even a two way? I'm leaving the middle pickup unhooked and just want to be able to select the neck and bridge hums seperately in the usual positions. I guess my question is which lug on the switch do I connect to the volume pot? Do I need to bridge any of the other lugs on the switch? This is a RG550 beater. Thanks for any help.
