Harmon Swingmaster Trumpet Wow Wow Mute

Classic swing-era “wow-wow” sound.

The Harmon Swingmaster Wow-Wow mute brings a smoky, vintage jazz character to your trumpet. Designed with the classic Harmon-style cup and stem mechanism, it gives you expressive wah-wah effects used in big band, swing, and solo jazz playing.

Built for tonal richness and control:

• Made from copper or aluminum (depending on model) for a warm, resonant muted tone
• Includes a sliding stem that allows you to vary the “wow-wow” effect: push the stem in, pull it out, or remove it to change the sound texture
• Free-blowing design that does not significantly change the pitch, so you can use it reliably in performance without worrying about intonation issues

Expressive “character” tone:

• Produces a dark, smoky jazz sound—perfect for big band or swing contexts
• Versatile: get a soft, distant muted sound or a more pronounced wah effect by manipulating the stem
• Historically associated with classic jazz soloists, making it a go-to for authentic swing tone

Who it’s for:

• Trumpet players in jazz, swing, or big band
• Soloists who want flexible, expressive muted tone
• Any musician looking for a traditional Harmon-style wow-wow sound
