Yamaha's guitar effect pedal, Magicstomp, equipped with a variety of effects. Everything shown in the photo is included. I tested it by connecting an electric guitar, but I have not confirmed all functions, so it is being sold as a junk item. Please understand that there is a possibility that some functions may not work. Returns due to functional defects will not be accepted. - Brand: Yamaha - Model Name: Magicstomp - Function: Guitar effect pedal
