Co-designed with Kenny Rampton of the Jazz at Lincoln Center Orchestra, the world's best buzz mute just got better. The Hirschman Mutes Chicago Stinger Gen II+ is inspired by the buzz mutes of yesteryear, and has been redesigned from scratch with 100% custom components, engineering, and technology to provide the best intonation, slotting, playability, and BUZZ across the entire range of the trumpet at any price. This mute is a new, improved replacement for the Chicago Stinger Gen II. The Gen II+ finer caplet threads and added Tone Boosters improve intonation, slotting, volume, and projection vs. the Gen II.
