Cup Diameter 32.8mm
Helleberg-style cup suitable for most CC tuba playing. Rim designed by Warren Deck – one of the most comfortable rims ever made, featuring just the right amount of width and bite to give the player a sense of comfort and stability.
AT3U (Cup Diameter 32.8mm / Bore 8.20mm)
This new mouthpiece designed by Aaron Tindall is designed for use in all CC tubas. It has a deep Helleberg-style design with slightly straighter sides than the AT2U blending into a concave cup. The rim is designed by Warren Deck and is one of the most comfortable on the market. It features just the right amount of width and bite to give the player a sense of comfort and stability. This mouthpiece produces a rich and even tone across all registers.
The shank of this mouthpiece has been very carefully engineered to fit all tubas with the standard ‘Euroshank’-type fitting. Original lead-pipes from Meinl-Weston and B & S were used in this process. The exact matching of mouthpiece and instrument leadpipe is vital to achieve the correct response from modern German tubas.
