Tsarath 3x2 This is a small booster/preamp that pursues the blackface sound of Fender. It sounds great when left on all the time, set to a slight crunch. It's recommended to use it like a clean booster. There's a video on YouTube that introduces the product, so please refer to that. This is the main unit only. No instruction manual, box, or other accessories are included. It has been used, but it works well. Since this is a used item, returns are not accepted. Thank you for your understanding.
