I bought this new at the time and used it a few times at home, and then stored it. All accessories such as the box and adapter are included. Although it is a used item, I think it is in pretty good condition for its age. Thank you. I'm hesitant to sell it, so please refrain from price negotiations. It works powerfully as a booster/overdrive. It features a thick sound and natural distortion. There is little loss of low frequencies or thinness of sound, and it is recommended for bass as well as guitar. ■ Type: TUBE BOOSTER/OVERDRIVE ■ Equipped with 12AX7 ■ Controls: DRIVE, OUTPUT, VOICING ■ Switches: ON-OFF, FACTOR1-2 ■ Power supply: AC power supply included
