Rare 1957 Magnatone Mark IV. This is a Paul Bigsby designed instruments that utilizes a neck through construction and a semi hollow body. Light weight and super resonant. This guitar is a pleasure to play. It has a distinct sound that is sparkly and has lots of clarity. Great for song writing and chording. It is structurally in fantastic condition but is missing a couple of the plastic parts. The pickguard and truss cover are not intact. Neck is straight and the pickups are strong. one pot is changed, the other dats to the 27th week of 57. Comes with the original case. Great find.
