Yamaha BL-58L Bass Trombone Mouthpiece | Piano Gallery, Idaho Falls

The Yamaha BL-58L bass trombone mouthpiece delivers rich, velvety low-end sound with outstanding flexibility for symphonic and orchestral performance. This large shank mouthpiece features a medium cup and rim design with a 26.84mm inner diameter that provides easy playability through the low and middle registers with crisp attack characteristics. Professional bass trombonists and large-bore euphonium players appreciate its darker sound profile that's ideal for symphonic work and the semi-wide backbore that enhances the instrument's natural warmth.

Product Overview

Engineered specifically for bass trombone and large-bore euphonium applications, the BL-58L combines an expansive 26.84mm inner diameter with carefully optimized proportions for superior low register performance. The medium cup depth provides optimal balance between ease of playing and rich fundamental tone production, while the semi-wide backbore reduces brightness to create the velvety, darker sound that symphonic repertoire demands.

The medium rim design ensures comfortable playability during extended symphonic works without sacrificing precision or control. The 58-size cup proportions work in harmony with the semi-wide backbore to create exceptional flexibility and outstanding attack characteristics across all dynamic levels.

Yamaha's precision engineering delivers consistent performance that professional orchestral players worldwide depend upon for demanding repertoire. The BL-58L's darker sound profile makes it particularly effective for symphonic bass trombone parts and large-bore euphonium applications where rich, warm tones are essential.
