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
Widest in the Schilke bass range. More lip inside the cup means more volume down low and more endurance cost up top.
Detail 02
Wider than the 19/64 on the 58 and 59. Blows freer with less back-pressure, so it takes more air to control.
Detail 03
Fits large-bore tenor and bass trombone receivers only. A small-shank horn will not accept it without an adapter.
Detail 04
Feels slightly warmer and grippier on the lip than silver. Choose it if silver plating irritates your skin.
Detail 05
Half a millimeter wider and a bigger throat than the 59. The step up is real, not cosmetic.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Only if it's a large-bore tenor with a large-shank receiver. Even then the 1.143" cup is a bass diameter and will feel unwieldy for tenor work.
The 60 is wider (1.143" vs 1.123") with a 5/16 throat instead of 19/64. Bigger sound, freer blow, and more demanding on air and chops.
No. Schilke lists this as their largest bass mouthpiece for the experienced player. Students are better served by the 46 or 47.
The difference you'll notice is feel and skin contact, not tone. Gold sits a little softer and grippier; pick it if silver bothers your lip.
