Hi everyone. I’ve recently felt I should change mouthpieces due to some response issues I’ve had. Lately, I’ve been playing on a Schilke 52D. I really like the rim size and feel. I adore the color, power, and endurance I can achieve with the mouthpiece. I also don’t have any real issues with range on the piece, as I can consistently hit and sustain notes like B5 and F5. My problems, however, start to manifest when I am forced to play sixteenth notes at near octave intervals(fingerings changing of course) at anything past quarter equals 105 or so. My notes simply do not come out quick enough. I have two possible ideas of mouthpieces I could switch to. First, I have heard good things about the BB1’s response and color, but the rim size is smaller than what I am used to. Second, I believe a modified Perantucci 4-C with a beveled inner edge may be a solid option, making it slightly wider and having better response while still retaining its massive 8mm backbore. Any feedback or suggestions would be greatly appreciated.
