Designed exclusively for tenor trombone. The Warm-Up Jr. delivers the same core benefits as the aluminum Warm-Up Mute—quiet practice, stable intonation, and natural response—using a lightweight plastic body for easier handling and greater accessibility.

Product Description

Warm up anywhere, at any time

Transform nervous energy into excitement.

The Best Brass Warm-Up Jr. Mute is a compact, ultra-quiet practice solution designed specifically for tenor trombone players who want the benefits of the legendary Best Brass Warm-Up Mute in a lighter, more accessible form. Whether you’re warming up in a hotel room, backstage, or right before a performance, it allows you to play naturally without disturbing those around you.

Same concept, different material

The primary difference between the Warm-Up Jr. and its aluminum counterpart is the construction material. The Jr. uses a high-quality plastic body, making it lighter and easier to manage while preserving the same balanced resistance, stable intonation, and natural airflow that define the Best Brass warm-up experience.

TromboneLAB’s Take

Why we like it:

I love options—especially when those options deliver the full Best Brass experience at different price points. If dropping over $100 on the aluminum Warm-Up Mute isn’t your move, but you still want a practice mute that won’t hold you back, Best Brass has you covered.

The Warm-Up Jr. delivers the same quiet, free-blowing response and stable intonation as the aluminum model, just in a lightweight plastic body that’s easier on the budget and easy to live with day-to-day.

If you’re a tenor trombonist who needs a no-nonsense practice mute that actually lets you get real work done—without fighting resistance, pitch, or feel—this is a rock-solid choice.

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