Schilke Jon Faddis XL Mouthpiece

Out of all of my "lead" or "cheat" mouthpieces, this one has a very "meaty" in low register, so big and "meaty" it puzzles me. I understand that the rim is similar with a 7C, but compared to Bach it's rounder and allows you to press without cutting into your lips (don't press, use air, pressing it's a bad habit).

It sounds heavenly in the high register, has a very sharp sound, but it doesn't sound nasal in medium and low register. My "go to" lead mouthpiece lately.
