that switch that Ibanez uses for the "special 5-way" wiring scheme for two humbuckers is not a widely available part. you could try ordering that exact switch from an
Ibanez dealer, or see if rich @ ibanezrules.com has one in stock, but you won't find a common replacement part at GC or something. the only way to get those exact combinations using a readily available switch is to get a 24
pole switch from dimarzio or fender or stewmac and wire it up with lots of jumpers.
the closest switch to that is the P model Schaller Megaswitch that stew mac sells [
www.stewmac.com ]. it has the same combinations as the PRS rotary switch, and three of the five are in the Ibanez special 5-way scheme.
