SOLD Prototype CHI Tony Kniffen Mouthpiece

This is the first prototype made for Tony and even though after a lot of playing on it we are working a completely different model for him this was very popular with everyone that tried it and has become our CHI Brass R Helleberg Model now.   The prototype has wear on the rim, scratches in the cup scratches on the outside of the cup but is in perfect playing condition.

This mouthpiece works very well for those wanting a medium width but deep cup on large CC and BBb tubas and it also works quite well on large EEb tubas.

This one has standard shank
