A Gibson 7-String resonator? Your eyes do not deceive you! This prototype guitar is a one-off that never made its way into production. Expressed in a letter that comes with the guitar, George Gruhn suspects it was a trial from the Gibson Kalamazoo shop made with parts from their subsidiary Valco. This instrument comes with documentation in the form of a Guitar Player Magazine article and a printed article with George Gruhn. This Resonator is constructed using a spruce top and mahogany back and sides. The resonator cone and parts are suspected to be left over Valco parts from the 1930's assembled into this guitar in 1950.
The guitar comes with a period correct hard case
