This is the Phil Jones Bass Bass Buddy bass headphone amplifier. Everything is included except for the outer box and manual (dedicated carrying case, AC adapter, stereo mini-cable, and two conversion connectors). It has been stored in its dedicated case since purchase with almost no use. The rubber equalizer knobs have hydrolyzed and were removed, so if you need them, please purchase them separately from a JES shop. There are no other noticeable scratches, but please understand that this is a used item. - Model Name: BASS BUDDY - Brand Name: PHIL JONES BASS - Input Terminals: Bass Input - Output Terminals: Headphone Output - Controls: Volume, Compression, Equalizer Thank you for looking.
