C Contrabass Tuba 6/4

Built with the original tooling and molds of Hirsbrunner, Adams re-designed and improved the legendary Yorkbrunner. The instrument is known as one of the best replicas of the legendary York 6/4 CC tuba.   

The C Contrabass Tuba 6/4 is the larger version of the C Tuba 4/4. The geometry of the Adams C Tuba ensures an extremely powerful and dark tone with plenty of core.

When testing and adjusting the C Contrabass Tuba, Adams focused on crafting an instrument with great projection and rich overtones that would sound impressive in any large concert hall.
