NEW ARRIVAL In the mid '30s, Gibson luthiers decided to build the best-sounding, most powerful flat-top acoustic ever. The result was the Advanced Jumbo. What Gibson’s luthiers discovered was a resonance-enhancing, advanced X-bracing pattern that had not been used before. The results were a deeper bass and increased projection. During the three years the AJ was in its first production run, Gibson made about 300 of them. It wasn't until 1990 that Gibson reintroduced the AJ and their value as a vintage-tone time capsule was recognised. The AJ offers rich harmonics with excellent punch and presence. The spruce top and rosewood back & sides are finished with a simple, single-ply binding. A traditional sound hole rosette, mother-of-pearl diamond and arrow inlays are handset in the rosewood fingerboard and the classic MOP script logo with MOP vertical diamond and arrow inlay make this instantly recognisable as a classic. This example - in a very rare natural finish - is in excellent condition, with very little visible playwear. It comes in it's original Gibson embossed hard case.
