As with all Hohners this is a loud instrument, especially for a two reed instrument. It has bassoon and clarinet reeds on the treble and you can select either one or both. The bass is deep and it has a low A. Compression is excellent. This is a nice light instrument that plays very well. Weight is 13 pounds, keyboard length is 15.5 inches. it comes with a hard case and a 6 month warranty.
