if i understand what your saying correctly, it wouldnt effect the playability of the guitar, but it would ruin the look, you would have a mini "moat" going around the trem, which would make it look a lil odd and not very jem like.
dya get what i mean
btw, that guitar looks ace at the moment, youve got the rg shape just PERFECT, keep up the good work, im hooked on this topic, i check it everyday hoping for updates , im an rg/jem fan
oyea, btw i think you should go with a reverse headstock, theyre cool imo, check this pic out:
