This Collings 01 12-fret is just into the shop on trade! We've seen the Walnut / German Spruce tonewood pairing on many of Collings' small-bodied guitar, and the results are consistent -- sublime clarity, with a glassier, rounder tone than this guitar would have were it built with Mahogany. A 12-fret 0 invites a certain sort of playing style ~ this isn't a guitar you want to sit down and hammer with a flatpick. And when played fingerstyle, this little guitar is capable of producing gobs of sound that would fill up space on a recorded track beautifully.
