I have a PRS and a Strat. My Seat weighs close to 8.5 lb.s and my PRS weighs close to 7 lb.s Its very noticeable wearing and playing them. Since I have learned a bit about Billy Gibbons that he hollows out his guitars and plays very light strings this has made me question what I thought I knew about guitars.. I thought a heavier guitar would have better tone and sustain, thats what I thought. After considering the sounds that Gibbons, and Hendrix I think I have been wrong. I bought my Strat in new condition but didnt give the weight any thought when I bought it. Whats your opinion on guitar weights, does it matter one way or the other?
