As with all TrumCor products, the Vintage-Tone is designed to be free blowing. It is in tune throughout the complete range of the trumpet. TrumCor has solved all of the quirkiness associated with the original Shastock Solo Tone mute. Our design compresses the air, speeds it up, and projects the tone for an exciting effect. A must for big band, Broadway shows, and the recording studio, TrumCor’s Vintage-Tone is quite possibly the most fun mute you will ever play!
