I get asked this question every time I sell a guitar. Yet I don't believe I've ever actually sold a guitar after giving an answer. I can understand if it's some one-off build that people aren't familiar with, but if it's your normal make and model, What's the deal? Never once have I seen someone carrying around a set of scales in a store in order to determine if that Tele, Strat, Les Paul... you name it... was actually worth the scratch because it was a few ounces off. If you can't handle the weight then play keys. Rant over.
