I need to get new pickups the guitar is an ibanez 542r. It has the body style of a satriani guitar with standard fender style tremolo. The neck is bolted on and it says "custom made" on the fretboard which is light in color and appears to be rosewood although I am not sure. I can not find out much about this guitar. It has stock single coil humbuckers and I play 9 gauge strings with it tuned either standard or dropped a half step. I do not have a clue what PU model would sound good on this guitar. I play mainly metal/rock and I have never seen anyone that does with single coil size humbuckers. This is a beautiful guitar with a really nice neck but the tone of the PUs are horrible. Is there a good warm sounding PU? Would a JB jr be a good choice?
