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!
