I got a Ibanez JS on ebay in 2007. I don't know what kind of JS but I think its a JS1. It has no serial number. but I have a pic. maybe you can id it from the photo. I also have a problem with the Floyd rose, I bought a Edge 3 for it but I find that the fretboard radius is kinda roundish. is it really like this or do I have to bow the truss rod a certain way so the fretboard is flatter. here is the photo...
