My friend bought a Gibson Studio SG. It's one of the 2002 ones with the ebony fretboard and the moon inlays. He thought he was getting a great deal from someone who didn't realize that this fretboard is kind of raising the value to collector's on these models. He paid $300 plus shipping, and he's happy as a clam because these things go for $500-$600. So he opens it up. No fret wear. No buckle rash. The thing looks like it's never been played. Except, of course, for the thin hairline repair evidence at the head-stock! So this Craigslist character has disappeared, of course. My buddy wants to get rid of this guitar, but be honest about the repair. So what do you guys think? Is it still worth $300? Any ball-park figures? I have zero experience with head-stock repaired guitars. Thanks!
