Guild's orchestra-body F30 Aragon Acoustic- Electric with D-TAR Pickup System is based on the 1956 F-30 Aragon guitar, with all solid woods, a red spruce top and bracing, mahogany back and sides, Indian rosewood fingerboard and bridge, bone nut and saddle, bone bridge pins, tortoise binding, 1-11/16" nut and lacquer finish. The D-TAR Wave-Length Pickup and Preamp System combines a thin, piezo under-saddle transducer with an 18v, low-noise, high input impedance preamp, to create a system with twice the dynamic range of typical 9v systems. The 18v preamp is powered by two "AA" batteries and a voltage converter. With 18 volts, the signal has more headroom, so hard strumming won't distort as easily. The preamp also has an input for a second source, like a magnetic pickup or a soundboard... Less
