The Blessing 6.5AL is a large shank trombone mouthpiece designed for intermediate and advancing players who need a more versatile, fuller-sounding mouthpiece than the student-level 7C. The 6.5AL designation indicates a slightly wider cup with a medium-large depth that produces a richer, more resonant tone while still being manageable for developing players.

The large shank fits tenor trombones with large bore slides, which is common in intermediate and professional models. The silver-plated finish provides a comfortable playing surface. The 6.5AL is a popular step-up choice for players moving beyond their first mouthpiece, offering a noticeable improvement in tone and projection while remaining comfortable to play for extended rehearsals and performances.
