BachCommercial Series Shallow Cup Trumpet Mouthpiece in Silver 5S
Independent shopping perspective
The Korena take
Built around Bach’s shallow-cup Commercial design, the silver 5S gives trumpet players a lead-focused option with projection in mind. Its #27 (.144-inch) throat and modified comfort rim pair a flatter rim top with an exterior profile drawing from Bach Standard and Mega Tone designs. It is part of a two-cup Commercial range, allowing players to select between shallow and modified V approaches.
