BachCommercial Series Shallow Cup Trumpet Mouthpiece in Silver 3S
Independent shopping perspective
The Korena take
Bach’s silver Commercial Series 3S uses the line’s shallow-cup design for a lead-oriented trumpet mouthpiece with projection cited as a design goal. A #27 (.144-inch) throat is paired with a modified comfort rim featuring a flatter top. Its outer shape blends elements from Bach Standard and Mega Tone models, giving the 3S a distinct Commercial Series profile while retaining the shallow-cup configuration.
