This is a G2.1u multi-effects processor from ZOOM. I purchased it new several years ago, but I haven't used it much, only a few times, and it has been stored since then. There is some damage to the box, and there are scratches on the pedal and sides of the unit from use. However, the knobs and switches are in very good condition, and it functions well. Returns are not accepted after purchase, so if you have any questions, please ask in the comments before purchasing.
