Problems with Ibanez '96 SR500 Bought a used SR500 a few weeks ago and am having some problems with the vari-mid system. One of the vari-mid pots (the middle frequency pot) didn't seem to work properly and there is a "dead Zone" on the D string from around the 4th fret to the 8th fret. The string just doesn't ring or sustain in that zone. The strings are less than two months old - Ernie Ball slinkies. I even replaced the D string just to make sure - no change. Also, even though this guitar has active electronics, it is not very loud with the amp. My passive bass is actually louder than this active one. I expected to have to use the attenuater on the amp input, but if I do, the bass can hardly be heard. When I opened up the preamp cover, I found two wires broken loose from the preamp board. I downloaded a wiring diagram from Ibanez and found that the original wiring in my preamp doesn't match their diagram. The board looks the same with the same solder connections, but, the wire colors to and from the pots are different - same colors, different order. So now I'm really confused. I re-soldered the broken wires where I thought they should go, but, who knows if it is right. The problems with the dead string and pot remain. Not sure what to do. I like this guitar, but it doesn't work properly. Can anybody explain the discrepancies in actual wiring vs the Ibanez diagrams? BTW, the diagrams for all their vari-mid systems seem to be the same. Maybe I should scrap the vari-mid and install some other pre amp? Or, can I get a new or used preamp board to replace mine with somewhere? Could the dead zone on the D string be caused by some other issue? Thanks for reading... I really want to fix this thing.
