Try this mouthpiece if you are playing a GR 64Z* and you bottom out or feel like you shut off. Also, if you play a Wick 5E and want improved articulation, sound, projection, and intonation with a similar feel, look at the 64E-5. If you play a Schilke 10A4a and you bottom out or feel like you shut off, this piece may be an ideal alternative.
