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.
