Designed in cooperation with tuba artist Aaron Tindall, the Ultra Series mouthpieces from Denis Wick offer a more-true tuba sound compared to any other mouthpiece available. Each mouthpiece offers improved articulation, endurance and intonation with a powerful sound in all registers, from low to high. Since the exact matching of mouthpiece and instrument leadpipe is vital to achieve the correct response from modern German tubas, the mouthpiece shank has been very carefully engineered to fit all tubas with the standard ‘Euroshank’-type fitting.
