I'd be amazed if it sounded like anything other than maple!
Which guitars did you see it on yesterday? Gibson by any chance?
Well, I suppose there's a possibility the heat treatment
might change the tone somewhat!
Yeah, saw a few of the new lower-end Gibsons (the '60s SG Junior, for one) at GuitarGuitar in Epsom. Nice shop! I didn't actually try anything though.
