This is a standard preamp from MXR. I am selling it to organize my equipment. I purchased it about two years ago and used it several times in live performances, but there is no scratchiness and it works without any problems, and the operation has been confirmed. I think it's relatively clean. Please note that Velcro is attached to the back. MXR M80 m80
