OMNI BOOST MK II effector with versatile gain settings. - Model Name: OMNI BOOST MK II - Power: 9V - Controls: GAIN, CLEAN, FAT, FLAT - Bottom: Cloth-covered - Design: Fish logo Thank you for viewing. Purchased in 2015. The plating is peeling off in some places. I have confirmed that it powers on, but I haven't been able to confirm if it works properly due to lack of equipment. Velcro is attached to the back. I can remove it before shipping if you request, but there may be residue.
