Guardala King mouthpiece / using Unfiled Jazz Select D’adario Reeds
i only practice up to and including altissimo D, the only problem notes i have are on altissimo B and altissimo Bb. i find some altissimo notes are more sensitive to how you position the reed on my mouthpiece, a slight adjustment of the reed position and alignment and they pop out a lot better.
i prefer reeds, you get them nice and soggy and you can start bending notes really slow, smooth and less harsh. The thing i find with altissimo notes, they work a lot better when you practice scales in the altissimo range giving you better control. it’s more the player with a lot of practice can play on any reed.
