Like new. Used for about 2 months. There is a tiny dent in the top of the heatsink that isn't really noticable unless you look at the right angle. I'd give it a 9/10 cosmetic, 10/10 functional.
Comes with original box, manual, etc.
There are no controls on this amp! Only gain. I does have dip switch that allows you to select between a 5.5v and 1v input sensitivity.
