Sound Booster [Wide] Acoustic Improvement for Brass Instruments

A set of 2 thick-type sound boosters for instruments with rotary valves.

As shown in the example, open the rotary valve cap, place the booster, and then close the cap.
This alone will change the way the sound resonates.
The way the sound resonates will also change if you switch the valves where you insert the booster.

The gold ones make the sound resonate more widely.
The silver ones make the sound's outline sharper.
And if you use both...

We offer three sizes: [Narrow], [Middle], and [Wide]. The effect tends to become stronger as the size increases, but a stronger effect is not always better. The optimal condition will vary depending on individual condition, compatibility with the instrument, and other factors.
We also offer a [Powerful] type, which has a different resonance.
We hope you will try various options and find your own best fit.

You may be skeptical just by reading the description, but we are confident that you will feel some kind of effect, as many customers make repeat purchases. We hope you will experience it for yourself.

*Please note that the perceived effect may vary from person to person.
