The G-600 Aspen is a 1993 solid-state acoustic-instrument amp from Guild's US Music era, built on the G-300 Tamarack circuit. A high-impedance input with active/passive switch and sensitivity trim feeds op-amp stages with level, treble, middle and bass, a switchable notch filter, spring reverb, and a bucket-brigade effect switchable between chorus and a Rototron rotary mode. It adds an effects loop and signal output, with two LM1875 power amps.
