I love my Hirschman Mutes! The KR Indigo MAX's adjustable Kenny Penny opens up a world of subtle tonal possibilities. The mute also looks cool and feels great in my hand. Since I started using it, many of my colleagues have ordered one. The Chicago Stinger Gen II buzz mute is a very fun mute to play, adds a whole new sound my toolbox. and has surprisingly good intonation!

“The KR Hirschman Indigo plunger mute is by far my favorite mute on the market! Its lightweight quality makes it easy to effectively create the traditional “wah wah” sound. It is also the ONLY plunger that keeps the horn in tune when it is completely closed over the bell.”

Brass players listen: I got this beauty from my good friend Kenny Rampton, a master in the art of plunger playing. He developed the KR Indigo Plunger with Hirschman Mutes and it is an absolute must-have. Only the Indigo has the Kenny Penny!

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.

"I am incredibly honored to be joining the team at Hirschman Mutes under the brilliant development and leadership of my friends, Kenny Rampton and Ed Hirschman. After exclusively playing the KR Indigo plunger and Chicago Stinger mute since their release, it is clear they are currently developing mutes for the discerning professional and sideman. In tune, responsive, evenness across registers and great sound are just some of the characteristics of Hirschman Mutes products. Not only that, but in a world where 3D printers and other forms of at-home manufacturing are all too easily attainable, Ed and Kenny are making mutes the way they have and should always be made. Looking forward to working with the team to see what’s next!"

You just HAVE to get the Kenny Rampton KR Indigo plunger mute! There really is no comparison.

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!”

Scotty Barnhart

Kenny Rampton’s new plunger mute is just great. The intonation is perfect, it fits nicely in my hand, and it’s easy to play in a variety of ways. I love it!

Tyrone Block

The KR Indigo Plunger is a wonderful fit for the sound I hear in my inner ear. It allows me to have a deep rich sound and simultaneously not diminish all the creative characteristics available. As a trombonist who loves to play plunger solos, I feel I have more sounds and nuances immediately accessible. At the same time, the finger slot is a magical touch, so it never slips out of my hand. Thanks for thinking about the little things.

Joe Boga

Thanks so much to Kenny Rampton for sending one my way and for all the thought that was put into its design. It projects great and plays in tune even when it's completely closed!

Randy Brecker

Hey All!...Great new Kenny Rampton Plunger Mute! Check it out!

Chris Crenshaw

“The grip, feel, look, and versatility of the Hirschman Mutes KR Indigo BIG BLUE plunger mute helps with all my plunger needs. It’s useful for solo and section work.”

Jeff Crouch

The Kenny Penny is so cool, it changes the sound quality and I’m still experimenting with which way I like it best. I’ll probably keep using this mute until I either die or it gets damaged, in which case, I’d get a new one. I think I’ll die with it still in near perfect condition.

You need one of these! Seriously the best plunger mute I've ever played!

Comparing with a variety of classic plungers from my collection, the new KR Plunger came out on top with regard to overall pitch and sound.... it scores big on hand comfort, appearance and versatility too.

“After many years playing the plunger (and playing a duffel bag full of different ones), the Hirschman Mutes KR Indigo BIG BLUE plunger is the best! The feel, size and intonation are AWESOME!”

Dan Miller

I love all of the attention to detail paid to developing this mute by Kenny, Ed and all the masters of plunger playing who contributed to its development.

Eric Miyashiro

やっと届きました！Kenny Ramptonのプランジャーミュートです！　　　音色を変えられる装置が付いているので早く本番で使ってみたいです。

James Morrison

The KR Indigo plunger is amazing! I was expecting a ‘better’ plunger - but it’s so much better that it makes every other mute obsolete. There’s a whole new world of nuances I can get due to the shape and flexibility of the material, and the ability to open or close the hole is gold (also the coin is very cool).

I find I’m choosing to play with the KR Indigo so much more than I would ever use any previous mute, it’s just got more possibilities and I can be more expressive with it.

Ed Neumeister

“The Hirschman Mutes KR Indigo 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.”

Marcus Printup

I’ve always had to teach students how to bend pitch in order to play in tune with a plunger. Bending isn't needed with the Hirschman Mutes KR Indigo because it plays PERFECTLY in tune. Great job Kenny...and you get the Kenny Penny!

Michael Rodriguez

Great mute Kenny, you nailed it! Thank you!!

Rashawn Ross

The KR Indigo plunger is everywhere!!! You guys Definitely did a thing with that mute. I know it's making a significant appearance on a trumpet solo on the upcoming Dave Matthews Band album. Nobody should ever use a regular plunger ever again. Kenny Rampton and Hirschman Mutes changed the game.

Arturo Sandoval

“It's the best plunger I've ever tried”

Jim Sheffer
