Symphonic and jazz players have always experimented with ways to create a darker sound by using various mouthpiece add-ons to add weight and mass. The Bach Mega Tone Mouthpiece takes these experiments one step further. To create the Mega Tone, we start with genuine Vincent Bach mouthpiece designs and more than doubles the outside mass. This darkens the sound and allows you to play at higher dynamic levels without distortion. Mega Tone slots extremely well so pitches center dependably, and a slightly larger throat affords less resistance and greater flexibility. The result is a warmer, more powerful sound that adds a new dimension to concert, pop and jazz playing. Bach Megatone Trumpet Silver Plated Mouthpiece, 1E. Cup Size 1E, Cup Depth Shallow,  Cup diameter 17.00mm, Rim Shape Medium Wide.
