Lots of people have asked if you can replace the 5 way switch in a HH RG for a normal five way. I can finally after a lot of research (and buying an RG7620
) say no and why!
The Ibanez switch SC/2502W is completely non standard! I have a schematic here:
This was determined by looking at the tracks from the back of the switch through the PCB.
The logic of the connections is this:
Pos 1 A -> D
Pos 2 A+B -> D, W+X -> Z
Pos 3 A+C -> D, Y -> Z
Pos 4 B+C -> D, X ->Z
Pos 5 C -> D, Y -> Z
Phew!
I've checked against the schematic for RG1527 from the Ibanez site and The schematic is correct with this switch, It gives:
Pos 1 Bridge HB (2 Coils Series)
Pos 2 Inside Coils Parallel
Pos 3 Neck HB and Bridge HB Parallel
Pos 4 Neck 2 Coils Parallel
Pos 5 Neck HB (2 Coils Series)
Blimey!
The only way you can replace this switch with something off-the-shelf would be to get a 5-way 4 pole megaswitch (same as Ibanez VLX91).
