Legends Mamba: This mouthpiece began with a scan of a rare DiOrio top. With an inside rim diameter this small, .580″, it is definitely geared toward upper register and commercial playing. The rim contour is round inside with soft bite. The cup is a very shallow V-bowl, similar in depth to a Bach F. Legends Brass has paired this rim and cup with a tight throat (#30) and Legends Manhattan backbore, which has a very focused sound. This mouthpiece isn’t for everyone, but it’s a deadly weapon for commercial and upper-register players who want to take their audience’s breath away!
