Bach Trombone Mouthpiece 6 1/2AL vs Schilke 51D Trombone Mouthpiece

Overall winner: Bach Trombone Mouthpiece 6 1/2AL

Key Differences

The Bach 6 1/2AL (A) has a medium‑deep cup and a wide, well‑rounded rim producing a rich, compact tone and sits in a more affordable price tier; the Schilke 51D (B) has an extremely large cup for a more powerful, euphonium‑friendly sound but can produce a darker, horn‑ or tuba‑like tone that won’t suit all players. Choose A if you want a traditional medium‑deep Bach sound and easier fit for many trombones; choose B if you need a very large‑cup, high‑power mouthpiece (including euphonium use)
