CC 6/4 tuba
The Adams CC 6/4 Tuba combines a colossal, resonant sound with impressive clarity and projection, making it the ultimate instrument for the largest and most powerful orchestral repertoire. Inspired by the legendary York 6/4 CC tuba and reimagined using the original Hirsbrunner tooling and molds, Adams has refined and enhanced this iconic design to set a new standard in orchestral performance.
Brilliant in tone yet solid in volume, the CC 6/4 is versatile and responsive, offering an inexhaustible wealth of sound colour to the player. Developed in close collaboration with professional tuba players, including Perry Hoogendijk (Royal Concertgebouw Orchestra) and Hans Nickel (WDR Sinfonieorchester), this instrument combines a rich resonance and solid low register with remarkable flexibility—exceptional for such a large tuba. Its unparalleled sound commands attention, making it the ideal choice for grand orchestral works.

A fully handmade instrument
To claim each instrument is handcrafted is a prodigious understatement. We are proud to be one of the few manufacturers in the world who master this craftsmanship. Driven only by perfection, each part is brought to life by the hands of our incredible instrument artisans.
The bell and body parts of our instruments are carfully made from sheet metal, assuring extreme hardness of the material, besides very thin and uniform wall thicknesses. Qualities that can't be achieved with the hydroforming technique used to produce cheaper instruments found in the market. Do you also opt for quality?
Unparalleled valve manufacturing
Made in the tradition of the legendary Bauerfeind valves, Adams valves are made from stainless steel for fast action and long-lasting durability. All valves begin with hand soldered brass valve ports and are finished on CNC grinding machines to tolerances of .005 mm, the tightest manufactured valve blocks in the industry. Experience the impact of these specifications on your playing comfort.
