Thank you for viewing. This is the Sonic Silver Peg, a bass preamp that captures the sound of the Ampeg "V4". - Model Name: Sonic Silver Peg - Brand: One Control - Control Knobs: Volume, Tone, Mid - Accessories: Box I am selling this to organize my equipment. Operation has been confirmed. There are no noticeable scratches on the visible parts, but there is a mark on the bottom where a sticker was removed (see image 8). If you are concerned, you can probably remove it by rubbing with a sticker remover.
