e-Brass III for Tenor Trombone

Designed for trombone players who want maximum sound reduction with a surprisingly natural, free-blowing response—plus the added advantage of an all-in-one electronic practice system.

Product Description

A fundamentally new acoustic design

Extreme versatility, and a new level of comfort.

The Best Brass e-Brass III is not a standard “warm-up mute.” It’s a purpose-built, all-in-one electronic practice mute designed for players who need serious volume reduction while keeping the instrument feeling open, responsive, and usable. If you’ve ever tried a practice mute that made everything feel blocked or stuffy, e-Brass is built to solve that problem head-on.

Why e-Brass exists

e-Brass was designed around three goals: superior sound reduction, a surprisingly free-blowing response, and a compact all-in-one electronic system you can carry everywhere.

The result is a practice setup that makes quiet playing genuinely comfortable—while also opening the door to modern practice workflows like playing along with accompaniment, building your time feel, and improving improvisation through Music Minus-One style sessions.

TromboneLAB’s Take

Why we like it:

This is my favorite electronic practice mute because it combines everything I love about the Best Brass Warm-Up Mute with the electronic features I actually need—packed into a lightweight, compact unit that fits right inside my bell for effortless storage and everyday use.

Most electronic mutes are bulky and make you deal with extra parts (like transmitter packs) just to get going. With the Best Brass e-Brass III, it’s all built in—so it’s truly plug-and-play.

And let me be clear: this is not “just another practice mute.” The e-Brass III is a full-on practice system built for real life—late nights, thin walls, hotels, shared spaces, you name it. You get serious volume reduction and a horn that still feels playable.

The best part is the flexibility. You can use it like a standard practice mute, or you can plug in and hear yourself with way more clarity—plus run music through the aux-in and play along with your favorite tracks. That means real practice, anywhere, without the mute turning the horn into a stuffy mess.

It’s the best of both worlds, and it’ll quickly become an essential piece of your gear. Wherever you are, with this mute, you’ll never miss a beat.

I love it, and I really think you will too!
