Three-part System

with interchangeable rim, cup and shank.
This system is most effective for combination.
By varying cups or shafts, various tone and playing qualities can be achieved.
This is very practical when changing to other instruments.
The embouchure is not affected, due to remaining on the same rim.
The cup depth ranges to a maximum of 30 mm; the maximum bore diameter is limited to 4.7 mm.
