AER Amp One bass amp, unbelievable sound for it's size and weight (29lbs), very good condition, I have never had a problem with this amp in the six years I have owned it. Comes with padded cover. Sells new for $1800, I will sell for $950 including US shipping. Paypal only. The AER Amp-One 1x10" bass combo pumps 200 Watts of power through a high-output 10” speaker for optimal performance. This single channel combo is highly portable. Great for live performances, the Amp-One has a dedicated line out perfect for additional support from a mixer or PA system. The Amp-One has enough power to fill the room with lush bass tone and won't take up a lot of real estate on the stage.
