A one-piece bell has an axial (lengthwise) seam, making it a continuous extension of the instrument's material. This results in pure, uniform resonance and superior tone. A hammered yellow brass bell produces a perfectly-balanced tone with quick response and extra presence due to advanced manufacturing.

Hand-lapping pistons and slides ensures an absolutely perfect fit and seal between the pistons and casing or slide parts. Such a perfect fit helps to achieve smooth air flow and smooth action and improve the response and intonation of the instrument.

Perfectly rounded tubing results in less turbulence and a smoother air flow, thus allowing for an excellent scale and reduced resistance.

A high-energy laser fuses the brass together for a virtually seamless bell which allows continuous, even vibrations.
