BOSS Multi-Effects Processor This is a BOSS GT-6. The main unit and the genuine AC adapter are for sale. I haven't used it much, and it's been in storage lately. I mainly used it for home recording rather than live performances. I have confirmed that it powers on and produces sound. Although the sound quality of multi-effects processors has evolved over several generations, I think it still sounds good, as it was the flagship model at the time. I thought it would be a waste to just leave it unused, so I'm offering it to someone who needs it. It's used, so there are signs of wear, but there are no major scratches or damage. Sold as is. No claims, no returns. - Model Name: GT-6 - Brand: BOSS - Connection Terminals: Input/Output Terminals - Features: Equipped with COSM technology
