A new kind of practice device.

Warm-up nano


Astoundingly small new SOUND TRANSFORMER. How do we use it???

Insert in any Wah-Wah(Ww) mutes!

Transforms Ww into a practice mute.

Just insert ‘Warm-up nano’in your Ww(Cool Jazz style*), and it reduces instrument output to a whisper while maintaining the full tonal characteristics of your favorite mute. The pitch, intonation, how it speaks...etc. All of which are kept as it is, so you can always practice with a familiar feel.
( Quietness depends on the mute you use. References at lower right. )

+ What is "Cool Jazz style" ?
The style of playing wah-wah mutes without the stem. We took its name from Best Brass Cool Jazz mute.

Place on any* mouthpieces!

( * Trumpets, Cornets, Flugelhorns )

As a Buzzing device.

Put your mouthpiece in Warm-up nano, and you can do a buzzing practice. Internal design of nano is accoustically well considered, and it generates appropriate resistances. As a result, your lips will get much more natural vibration.
With the accompanying strap-holder, it can hang on any bags or instrument cases. Now, hit the road and Warm-up anywhere at anytime.
( Notice: It does NOT mute the buzz sound.)

*** Look at this. Our dogs actually love it. ***

Note: Unfortunately, it does not mute their bark.

Notice: Unfortunately, it does not settle a big mouth.
