Initially chosen as a voice and steel-string guitar amp (high impedance input, tweeter). 48V phantom power - available on 3 inputs - very useful for my condenser microphones. The sound is quite neutral, clear and pleasant, more satisfying than some acoustic combos. Clever "all-in-one" concept, with enough inputs to rehearse with a keyboard, a second voice, a drum machine and/or bluetooth. Basic but usable equalization and effects. Expansion possibilities with outputs (passive speaker for more power, sub, monitor out) Negative points: transformer hum and buzz noticeable when close to the speaker, potentiometer action effective only on the last third of their travel.
