Detail 01
1.00 inch cup diameter
Mid-size for tenor. Schilke's line starts at .966 and runs to 1.143 on the bass models, so this leaves room either direction.

What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Mid-size for tenor. Schilke's line starts at .966 and runs to 1.143 on the bass models, so this leaves room either direction.
Detail 02
Wider than the 15/64 bore on the smaller models. More air moves through, so it stays open when you push volume.
Detail 03
Matches large-bore tenor receivers. On a small-shank horn it sits proud and leaks instead of sealing.
Detail 04
No number in the name means the standard rim. The 50C4 is the same cup with a wider semi-flat rim for endurance.
Detail 05
Smoother on the lip than silver, and worth having if silver plating irritates you on long rehearsals.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Large shank is the fatter taper used on medium and large-bore tenors and bass trombones. Small shank fits small-bore tenors. They are not interchangeable.
You can, but the 1.00-inch cup is small for it. The 57 doubles between tenor and bass, and the 58, 59 and 60 are built for full-time bass work.
Same 1.00-inch diameter, but the 50C4 pairs a medium-deep cup with a medium-wide rim and an F throat. The plain 50 is the standard Schilke cup and rim.
The 46 is Schilke's beginner model, with a smaller diameter and a rim shaped for flexibility. The 50 assumes a developed embouchure.
