No noticeable weight to be concerned with.I believe it does solve a issue. I have stripped the allen clamps on 3 sets of locking nuts! Having one that doesn't require a allen wrench ( that easily gets lost or misplaced right when you need it) ...priceless.. One less thing to worry about, that could TOTALLY mess with my head on stage...as long as it doesn't make my guitar neck dive ...How heavy is it?
