Keeley TS-9DX Thank you very much for viewing. This is the Keeley Mammoth TS-9DX. What I'm sending is the main unit and two rubber feet. The rubber feet were removed when I put it on a board and attached Velcro, so I'll leave it in this state. Please understand that this is a vintage item. No claims, no returns. A rare masterpiece based on the TS9DX model. The mini switch in the center allows you to switch between Mod Plus and Baked. By combining the original 4-mode switch, you can set a variety of sounds. This model is affectionately known as the "Frankenscreamer."
