Thank you for viewing. This is the BLUE 360 AIAB, a bass preamp from One Control. It's an AIAB (Amp In A Box) pedal that recreates the sound of the Acoustic 360 bass preamp and 361 cabinet. - Model Name: BLUE 360 AIAB - Design: Blue wave pattern - Control Knobs: Treble, Mid, Volume, Bass - Switch: Footswitch - Condition: Overall, there are small scratches. There are also rubber feet attached to the bottom by the previous owner, so it is listed as slightly scratched. I am selling this to organize my equipment. Operation has been confirmed. Thank you.
