JAMES SOMMERVILLE Model
The inner rim size is fairly narrow, for
enhanced flexibility in every range,
while the semi-flat rim contour gives
tonal clarity. The V-shaped cup adds
security to the high range while the
open throat size allows rich full-bodied
tone in any dynamic.
THOMAS BACON Model
This mouthpiece has a wide inner rim
diameter with a large V-shaped cup.

PETER SULLIVAN Model
The Sullivan mouthpiece offers rich
orchestral sound with a powerful tonal
projection. The rim and cup are fairly
large for comfortable fortissimo, yet
the mouthpiece also offers fine control
for the most delicate passages.
