Since I bought this amp I never have a problem with it, I only send to service for clean the controls, the display iluminated still works.
I use this amp as a monitor with a PA. I used it only a couple times in a party Gig with no PA (in a small room) and it's louder.
I been used with a Peavey 1x18" BW Cabinet and a Hartke 4x10" cabinet and works fine but the amp have a little distortion in hi volume. Recently I bought a new amp (Hartke 3500 ) since it has a minor distortion, I stop to use the Acoustic amplifier.
But anyway in the present it's a good amplifier to start.
