You shoud check the pickups and wiring section. I jsut got a bunch of useful info about how to wire the guitars. I have the otax 24
pole switch in my guitar.THe consensus is tha the switch is actually a good one but takes alot of care to wire correctly.
Ibanez has the stock
wiring diagram .Check that out at ibanez .com
The V8 in the bridge is 3 wires.One hot, one tap, and one ground.THe V7 neck is 4 conductor.All oyu have to do to get DImarzios in there is wire the corresponsing colors exactly where the existing V8 and V7 are.
You wont be able ot do a good job unless you loosen the switch and work on it like that
