Thank you for viewing this product! It has been used carefully indoors and stored in a case after use, so there may be some minor scratches, but I think it is in very good condition for a product of this age. A dedicated AC adapter is included, and it works without any problems. The BOSS ME-8 is a multi-effects unit for guitarists that combines a variety of effects into one unit. Despite its compact size, it is equipped with a wide range of standard effects such as distortion, chorus, delay, and reverb in high sound quality, and you can freely combine them to suit your playing style. The intuitive knobs and pedal layout make switching during live performances smooth. Furthermore, it offers a high degree of freedom in sound creation, allowing you to pursue your own unique sound. The robust body ensures long-term use, and it is a versatile unit that can be used from the stage to practice. Please refrain from purchasing if you are concerned, as this is a used item.
