Marshall's AS50D is a 50-watt, 2 x 8" acoustic guitar combo amp with 2 channels, including a phantom-powered microphone channel. It features a redesigned tweeter, digital chorus and reverb, and an anti-feedback notch filter. Each channel sports its own volume, EQ, FX loop, and D.I. output. Master volume, line out and RCA inputs round things out nicely.Please message us if you have any questions.
