Probably Gibson's best sounding (by far!) guitar of the period, and extremely rare. They called it their Folk model, able to be strung with steel or nylon strings with a two inch wide, 12-fret classical style neck and extra light bracing. We needn't concern ourselves with the idea of nylon strings - that was mere marketing or misinformed makers. One unique feature is the maple back & sides, and with the lighter construction it gives an unusual and very beautiful tone, unlike any other Gibson.
