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
Fits large-bore tenor and bass trombones. It will not seat in a small shank leadpipe.
Detail 02
Wide cup. More lip vibrating means a bigger low register, but it takes more air to fill.
Detail 03
One of the wider rims in the series. Spreads pressure for endurance at the cost of some flexibility.
Detail 04
Large throat. Less resistance and more volume ceiling, but it can feel open on a light day.
Detail 05
Straight-walled bore section that keeps the sound centered and even rather than spread.
Detail 06
Slicker, warmer feel against the lip than silver, and an option if nickel or silver irritates your skin.
Final check

Product questions
Straight answers to the questions shoppers most often ask about this product.
Only if it takes a large shank. Most student tenor trombones are small shank, which needs a different mouthpiece from this series.
The 3AL is bigger: 26.40mm cup versus 25.73mm, and a wider 6.80mm rim. The 5AL is a tighter, more tenor-focused setup for wind ensemble work.
Mainly feel and skin comfort. Gold sits slicker and warmer on the lip and helps if silver or nickel irritates you. The cup dimensions are unchanged.
Yes. The wide rim and full low register suit euphonium, provided your instrument takes a large shank receiver.
