The B51 is a 51 key single action Bass with a range from C2 to G5. It is primarily designed for ensemble playing. 
The "fish tail" reeds mounted on raised MS58 brass frames provide instant reed responds at low air consumption. The equilibrium of the B51 is 'bass favored', perfect for ensemble playing. For solo repertoire please see our Parnassus 53 key double action bass model.
