High-quality graphic equalizer EQ-200, perfect for sound quality adjustment. - Model Name: EQ-200 - Brand: BOSS - Year of Manufacture: 2019 Thank you for viewing. After purchasing new, I used it a few times live, but then switched to a multi-effects unit, so I haven't used it and it's been in storage. (I used it with a bass guitar) There are no scratches and it's in beautiful condition. Please check the photos for details. (Please note that this is a used item)
