The Michael Baker Signature Piccolo Trumpet Mouthpiece features an inner rim ID of 16.50mm / .650” with a medium round rim contour. The mouthpiece is based on an unusual Bach "3" sized Cornet mouthpiece initially copied for him 20 years ago. The cup design is incredibly unique. Even though the standard straight numbered Bach cups are usually deeper and bowl shaped, this cup is a ‘C’ depth with a VM shaped cup. There is room off the rim and then transitions down into the VM shape leading to an open throat entrance. The throat bore is a #26 and the backbore is fairly open, which balances out the mouthpiece.
This mouthpiece is everything you could wish for in a Piccolo Trumpet and Eb Soprano Cornet mouthpiece. The sound is full and resonant with a perfect balance between the core and overtones in the sound. The response is immediate and projects well. This mouthpiece works well for Bach's Brandenburg Concerto with ease of production in the high register coupled with a pure clear sound.
