Selling to organize my equipment. I used this at home, so it's in relatively clean condition. It has a switch hat attached, but I will remove it before shipping if you don't need it. This effector can be used for both guitar and bass as a buffer and clean booster. I used it with my bass. It gives the impression of expanding the sound range and making the sound more present. #bass #guitar #effector #4000pre #Zahnrad
