well, there is the ibanez GRX20, which is the exact same guitar except with a H/H configuration. but I'll look and see if I can't find an RG model or something that has a H/S/H pickguard. I'll be checkin craigslist and ebay for something to come up.
as for pickups, I have already decided on the Tone zone for the bridge, I just don't know what neck p/u to get. as for having a middle p/u to get clean sounds, well, I was planning on adding in series/parallel switching, and perhaps phase switching or coil taps, but I don't really know what those two are, they just sound cool.. lol
EDIT: the only ibanez I found that is front mounted with H/S/H configuration is the JEM so... I guess I'm looking for JEM pickguard, hopefully I'll be able to find one reasonably priced!
