Ultra Sound DS4 acoustic amp in excellent condition. Designed for acoustic guitar, mando and fiddle. 50 watts, two 8” speakers, 2 channels (at least one with phantom power), 16 effects assignable to either channel both of which can be used for either instrument or mic. Overall excellent condition but has 3 small nicks in tolex on one side. Don’t know weight but it’s very portable with one hand. Demensions: 13” H, 18” W, 10 1/2” D.
