Mega Tone starts with genuine Vincent Bach mouthpiece designs and more than doubles the outside mass. This darkens the sound and allows playing 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. NOTE: The inner contours are precisely the same as the original Bach Mouthpiece, allowing same basic playability. However, additional mass on the outside produces a darker, more powerful sound.
