Phil-Tone mouthpieces, made by Phil Engleman, are known to have awesome tone and a powerful and bright sound. The Phil-Tone Sapphire mouthpieces are great, as they are designed after the late Florida Otto Link Early Babbitt mouthpieces. These are known to have more brightness and power than the Slant Signature Otto Link mouthpieces, so they definitely have the power mentioned before. This specific 7** mouthpiece was modified from a .100 tip opening to a .108 tip, which opens up the sound more compared to the original models of this. Get this great mouthpiece at this wonderful price while you can!
