YAMAHA MUD-1004 DISTORTION effector, featuring four control knobs and 1/4-inch jacks. It's relatively rare. No box included. Since I haven't confirmed it powers on, it's being sold as junk. Will be wrapped in bubble wrap for shipping. - Brand: YAMAHA - Model Name: MUD-1004 - Function: DISTORTION - Number of Control Knobs: 4 - Input/Output Terminals: 1/4 inch jack - Special Features: MULTI BAND Thank you for viewing.
