The Liberty ligature fits all Theo Wanne metal tenor saxophone mouthpieces.
Its unique design holds it securely in place even during reed and cap changes. This fixed position, however, is adjustable to other fixed positions along the mouthpiece body.
The integrated, 2-point, low surface area contact with the body of the mouthpiece allows it to also vibrate freely with the reed, improving the overall sound of the mouthpiece. It is both held securely in place and free to vibrate at the same time!
