Yamaha THR10 II and RELAY G10T II set. I bought these but haven't used them because I'm using a different amp, so I'm selling them. I've only used them once, but they are still considered used, so please purchase only if you understand this. I purchased them from Shimamura Music, and I will include the sales certificate sticker. I've discarded the amp's styrofoam packaging, so I will wrap it in bubble wrap and ship it in the cardboard box shown in the images.
