but it will be very difficult to do that on the saga kit. afaik, the top is veneered but also sealed, and it is near impossible to sand the sealer off in order to get to the veneer without actually going right through it. you might want to just sand it right off, re-veneer with your own stuff, etc. this was the most common complaint i've read about the saga prs style kits... that being said, whatever you end up with will be totally playable.. the kits are a fun way of gettin' into things
