This is an original RG DYNAMIC PROCESSOR, PRO-20. Told it works great and it appears very clean. Had to be removed from a home that was recently sold. No dings or scratches and the sticker on the back is complete that says PRO-20, 20-2822. Camera reflection makes it appear the label is only half there, no damage to the label or anything I can see. In checking out the unit, most have the name Pioneer together with the RG. There is no mention of Pioneer anywhere on this unit. Shipping $14.95, USPS Priority.
