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 rim for a tenor player. Big enough for a broad sound without the endurance cost of a bass-trombone rim.
Detail 02
Darker, rounder tone and stronger low register. Costs you some ease in the upper range and demands more air.
Detail 03
Wider than average, so more air moves through. More volume and body, less resistance to lean on.
Detail 04
Straighter taper than a V-type. Adds core and projection rather than the softer, spread quality of a V.
Detail 05
Fits large-bore tenor and bass trombone receivers only. A small-bore horn needs the small-shank version.
Detail 06
Warmer and slightly slicker on the lips than silver. Also 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 your horn has a large-shank receiver — typically large-bore tenors and bass trombones. Small-bore horns need a small-shank mouthpiece; Denis Wick makes those in a separate line.
The 5AL has a slightly larger cup (25.73mm vs 25.40mm), wider throat, and a barrel backbore aimed at projection and symphonic work. The 6AL runs a medium backbore for even tone and an easier high register.
It changes feel more than sound — gold sits warmer and a bit slicker on the lips. Its practical advantage is for players whose skin reacts to silver plating.
Not really. The deep cup and wide throat favor a dark, projecting orchestral sound. Lead work generally calls for a shallower cup and brighter response.
