Sleeves and Tone Boosters allow you to customize your horn to give you the response and tonal qualities you want.

Bob Reeves Sleeves allow you to “fine-tune” the gap between the end of your mouthpiece and the beginning of the leadpipe to enhance sound, response and intonation.

Curry Sleeves and Denis Wick Tone Boosters add mass to your mouthpiece to improve slotting and to help reduce the loss of vibrations through the metal of the mouthpiece and channel them into the instrument.
