The Martin GPC-28E acoustic-electric guitar gives you the comfort and tone of a Grand Performance body style with a natural DI sound for stage and studio convenience. The GPC-28E has the warmth, balance, and projection of a Sitka spruce top on an East Indian rosewood body with the clear articulation of an ebony fretboard to breathe new life into your arrangements. Onboard Fishman Aura VT Enhance electronics with hidden volume and tone controls deliver a big, lively direct sound without detracting from the natural beauty of your instrument.
