The
Buchholzbird (literally:
beech tree wood, but it's still made from korina
) is not only a one-off, beautiful and celebrity-connected, but also sounds great, a rare combo in my experience. It has that really warm, yet distinct, velvety tone, it "sings" all over the fretboard and invites legato playing. Would have been a dream as a fretless.
That Gibson never opted for a fretless TBird in all those decades of production baffles me - it's like a TBird from its wood and construction is made for just that.
