This is a vintage and rare Drum machine made in Japan in the 70's. The MR-101 is a very tight & bright sounding beatbox. Not much hiss or hum compared with other more popular boxes. With 20 base beats available, there's plenty of variety & it definitely has a unique sound. - There are 3 variations total for each of the first 5 beat buttons. Works great! swing by and check it out!
