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
Far more open than the 26 and 27 throats on standard trumpet pieces. Takes more air, gives more volume and less resistance.
Detail 02
Four widths in the line. V1 is the widest, then V150, then V2, with V3 the narrowest.
Detail 03
You can match your current mouthpiece by rim rather than guessing. V3 lines up with a 3C, V1 with a 1C.
Detail 04
Cornet pieces run deeper and more funnel-shaped than trumpet pieces. That shape is where the rounder cornet sound comes from.
Detail 05
Slicker on the lip than silver and non-reactive, which matters if silver leaves you red or itchy.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. Cornet mouthpieces use a shorter, smaller-diameter shank that won't seat correctly in a trumpet receiver. You need a trumpet mouthpiece for a trumpet.
It's a considerably larger bore than the 26 and 27 throats used on standard trumpet pieces. Less resistance, more air required, more volume available at the top of your dynamic range.
The V3, which is cross-referenced to a 3C rim. If you want more width, the V2 corresponds to a 1.5C and the V150 to a 1.25C.
Two reasons: it's a Symphony Series design rather than Standard Series, and gold plating adds cost over silver. The Standard Series silver pieces in the same brand start well under a hundred dollars.
