Excellent powered bass speaker for small gigs. I used it with a fishman preamp for upright and also for vocals with a mixer and or guitar for restaurant gigs. In a practice or rehearsal setting it works very well with electric bass also, but it was really perfect for upright gigs in a small room. I used it very often with drummers playing mostly brushes or sticks not super loud. It was on the NYC subway many times. It's missing one of it's rubber feet, you can see in the picture, but still balances well on it's side. 
Other than that it's in excellent condition. A very useful little swiss army box that I will probably regret selling.
