Edward’s 331CF tenor trombone bell that is yellow brass, 22-gauge, unsoldered rim, cryogenic-treated bell with K & M Stand. Please see pics.
The Edwards 331CF is an 8.5-inch professional tenor trombone bell known for its focused, responsive projection.
331 (The Model Number): The final digit represents the alloy. On this mandrel, a "1" signifies yellow brass(70% copper / 30% zinc). Yellow brass offers a highly consistent, clear timbre and quick response across all registers and dynamics.
22 Gauge (Implied): In the Edwards sequence for this family of bells, the 331 designates a medium-weight wall thickness (22 gauge). It balances the easy projection of a lighter bell with the stability of a heavier wall.
CF (Treatment): This stands for Cryogenic / Heat Treatment. It is a partial heat-treating process that relieves stresses in the metal. This allows the bell to blow freely and adds a broader spectrum of tonal colors to your sound.
Because it features an unsoldered rim (typical of the 321/331 sequence), the 331CF provides a wide, overtone-rich soundstage with excellent acoustic feedback directly to the player's ears. Articulations feel immediate and crisp compared to soldered alternative models.
