Bass Trombone: Underpart

The rim is only half the equation! Fine-tune your sound and support with one of our three cup depths—each designed to bring out the best in your playing.

Each cup requires the respective diameter rim.

Choose Your Size:
Our bass trombone models are available in the following rim sizes to match your playing style and preferences:

• 1 – Our largest rim, ideal for professional players accustomed to larger equipment.
• 1.25 – A broad mouthpiece offering strong support across all registers.
• 1.5 – A balanced, versatile option suitable for a wide range of playing situations.
• 1.6 – Similar to the 1.5 in feel, but with a slightly smaller rim diameter.
• 1.75 – Delivers a dense, compact tone while maintaining great balance and response.
• 2 – The smallest bass trombone rim in our lineup. Perfect for players seeking a more compact sound, or tenor trombonists transitioning to bass.

Three Cup Depths – Tailor Your Sound:
Each rim size pairs with a matching cup diameter, available in three configurations:

• D (Deep) – Our deepest stock cup. Offers a free-blowing feel and rich, warm tone in the low register without compromising upper register clarity.
• M (Medium) – Our most popular cup. A well-balanced option that suits a variety of musical genres and playing styles.
• S (Shallow) – Adds brilliance and efficiency, especially in the middle and upper registers, while providing excellent support.
