The Ultimate Trombone Mouthpiece
Comparison Charts

Note: Please do not take diameter measurements too seriously. Most of the time the difference in columns can be 0.02 of an inch (0.5 mm). Not much really. The measurements are done for comparison purposes of relative sizes. Attributes such as cup depth, rim shape, bite, and backbore also make a big difference in how a mouthpiece plays and feels.


In Alphabetical Order!
With Bach and Schilke at the top for comparison purposes
