Thank you for viewing. This item is the sumo stomp #9. It's a so-called Tube Screamer-type effector. It's almost new, having been purchased recently. I only tested the sound, and there are no scratches or anything. After buying a PRS Silver Sky, I wanted some effectors. I thought of following John Mayer and starting with the classic TS type. I was thinking every day whether to get an Ibanez TS9 or a TS808, and then I heard good things about this one and got it. I'm selling it to buy another effector, but it's an effector that really satisfies my desire to own it, so I might cancel the listing if I change my mind. The machined and anodized case is very beautiful. The machined knobs also feel cool and pleasant. Even opening the lid, the carefully selected parts are beautifully arranged, and I'm confident I could eat several bowls of rice just looking at them. I myself am someone who makes effectors.
