This is an Alesis "NanoVerb" reverb unit. I used it with an acoustic guitar. Since it was set on a board, pads are adhered to the bottom. They may not come off cleanly, and I've left them on as packing material for shipping. It works perfectly. I am the original owner, having purchased it new. Some people really like Alesis reverbs, and I think this one is simple and easy to use. Considering the price, I think it's a good piece of equipment.

If you are concerned about it being used, please refrain from purchasing. *Please refrain from price negotiations. *No claims, no returns. *Due to work, it may take 2-3 days to ship.
