Thanks for the feedback Scoville! The guitar is my 1975 Rob Armstrong 6/12 string doubleneck acoustic. Spruce top, figured maple back and sides, unstained macassar ebony fingerboards and bridges, Brazilian rosewood bindings, hand made case by Rob. Bought it in a junk shop for almost nothing. It's one of a pair, this one is a blonde. The other one is a brunette, and is made from cedar and rosewood. Wish I knew where that one is! The sound is huge, and so is the guitar!
