Patrick Mouthpieces - Commercial Trumpet
FROM STEVE PATRICK:
Sizes
5ZM
The 5zm uses the same rim, 28 drill, and back-bore from our 5z mouthpiece with a modified V cup similar to our M cup commercial mouthpieces.
84M FR
The 84M is the same as the 85M (Mike Haynes signature model), but with a tighter entrance to the throat to help with range, endurance and projection. It is comparable to a Bach 6 or 7 inner diameter. This mouthpiece has a medium V cup design. This mouthpiece has more resistance than the old Jet-tones providing more endurance, better projection and an easier high end. The sound is full and resonant from the very bottom of the range to the top. The back-bore is matched perfectly to the top to give you a balanced mouthpiece.
84S FR
The 84S shares the same rim as the 84M and is comparable to a Bach 6 or 7 inner diameter. This mouthpiece has a shallow V cup design. This mouthpiece has more resistance than the old Jet-tones providing more endurance, better projection and an easier high end. The sound is full and resonant from the very bottom of the range to the top. The back-bore is matched perfectly to the top to give you a balanced mouthpiece.
91S FR
There would be no Bach inner diameter comparison to this mouthpiece that I know of, but if Bach made one, it would be around a Bach 14 inner diameter. This mouthpiece has a shallow V cup design. This mouthpiece has more resistance than the old Jet-tones providing more endurance, better projection and an easier high end. The sound is full and resonant from the very bottom of the range to the top. The back-bore is matched perfectly to the top to give you a balanced mouthpiece.
