This is a Sadowsky bass preamp. I used it in a home recording board indoors, but I'm selling it because I bought a new preamp. I used it for about six months, and didn't use it very often. There are almost no scratches. I removed the rubber feet to put it in the board. I have the removed rubber feet, so I'll include them. When I put it in the board, I put Velcro on tape that's easy to peel off, so there's nothing left behind. The serial number sticker came off during that process. I still have it, so let me know if you want it.
