Cheapest ???? Trumcor Trumcor Standard Stealth Series Tuba Practice Mute Medium – C Tuba 4/4 ????

This practice mute is unique in that it responds evenly in all registers. When used for warming up or quiet practicing, one experiences articulation compression that is similar in feel to those conditions found in normal playing. Trumcor’s Variable Air Flow System allows control over the amount of air that passes through the mute, thus giving players the ability to adjust both volume and resistance.
