The BOSS EH-1-2 Enhancer is an effects unit designed to improve sound quality. - Model: EH-1-2 - Brand: BOSS - Output Terminals: OUTPUT - Input Terminals: INPUT Thank you for viewing. I purchased this used about a year ago and have only used it a few times in live performances, plugged into the amp's send/return. Operation has been confirmed. There is no scratchiness, and it functions without any problems. The accessories are all that are shown in the photos. There are almost no scratches or stains. I am selling it to fund the purchase of new equipment. *Please understand that this is a used item stored by a private individual. Type: Electric Guitar Manufacturer: BOSS
