ZOOM G3X Multi-Effects Processor (https://www.zoom.co.jp/ja/products/guitar/g3x-guitar-effects-amp-simulator-expression-pedal) Instruction manuals and other information can be found on this site. I received this from an acquaintance about 3 years ago, but I haven't used it much and have kept it at home. I don't have much knowledge of guitars, so I don't know the details. There is no box. Only the AC adapter is included. Price reduction is possible after a while after listing. Thank you.
