World's Greatest Plunger Mute?

This mute is quickly becoming a customer favorite here at ACB!

Hirschman Says:

The Hirschman Mutes KR Indigo "BIG BLUE" Plunger Mute has been optimized to give the very best combination of sound, size, feel, pitch and flex money can buy. We are proud to include amongst our official endorsers the Duke Ellington trombone section.

In Tune! Better intonation that any other plunger in your mute bag, especially when switching between open and closed plunger. If only the great Al Grey was still with us! He said that old school, 20th century "tight plunger...causes a back-pressure against your air stream and it throws your instrument out of tune.....Some players find adjustments in their lip and air pressure to play through it; others simply learn to slip past it." We have reduced these problems with our innovative design.

BIG - Because size matters! The BIG BLUE is designed to work with both the tenor trombone AND bass trombone. Bass trombonists Dave Taylor and Earl McIntyre are two early testers and endorsing artists that gave invaluable feedback during the design process.

Kenny Penny™ venting system Some players like to drill a hole through their plungers (where the wooden stick was) and some don't. Others carry two plungers in their bag to have both. The Kenny Penny venting system provides one penny outside the plunger and another inside. Turning the outer penny closes the plunger hole with the inner penny. Kenny Rampton likes it closed for playing over straight mute and open for plunger alone. There's no right or wrong, and the Kenny Penny lets you discover your ideal sound...that's our "two cents."

No-Slip Hand Grip Our large, comfortable hand grip makes the plunger easy to pick up and hold. No more slips or drops!

Built to Last The KR Indigo is made of durable silicon and is much less prone to the drying out/cracking that occurs with many rubber hardware store plungers.

Distinctive Color Inspired by Duke Ellington's Mood Indigo and Snooky Young's/Clark Terry's blue plungers, with a design updated for the 21st century.

Players Say:

Wycliffe Gordon: “I love this mute! This is a great product for beginner, intermediate and advanced players because you don't have to fight with adjusting your air when you're playing. It has a penny you can use to play open mute or closed mute, depending on the sound that you like. It plays in tune, it stays in tune."

Ed Neumeister: “The BIG BLUE plunger mute is the most versatile plunger mute that I have ever played, and I’ve played many. The addition of the “Kenny Penny” valve gives the player flexibility for adjusting colors and timbres as well as intonation. Any brass player who is serious about playing with a plunger mute should have this mute in their arsenal.”

Dave Bargeron: “I was a faithful user of Kirkhill plungers all of my playing life until now. The KR Indigo BIG BLUE plunger is the perfect size, has the Kenny Penny valve and the feel around the bell is exceptional. It’s absolutely beautiful in color....Rich blue plays rich Blues!! And the squeeze is just right... I really love it!”
