Choose Your Size:
Our large bore tenor trombone models are available in the following rim sizes to match your playing style and preferences:
- 3 – Our largest cup in the large bore line. Very open and free-blowing with a dark tone concept.
- 4 – Very open and free-blowing. Great for orchestral 2nd part playing.
- 5 – Offers excellent core production and balance across all registers.
- 5.5 – Similar to the 5, but with a slightly smaller rim diameter for added support.
- 6 – Provides a focused sound and dense core. Excellent for players who prefer smaller equipment.
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.
