I ' m also having this problem after a yearslong layoff from playing . Using an otto link on a mark vi tenor . I just bought a rubber Lakey to see if that helps . I switched to softer reeds and that helped , as did pushing the mouthpiece all the way in , but that causes other issues . Given it seems to happen to people who are out of practice , it ' s probably mostly an embouchure issue , although I ' m excited to try cork in the bell . <| sep |> I would venture a guess that you ' d need a sub who penetrates shields ? There ' s a Good and Great shield in that wave , sadly . <| sep |> No root necessary . Instructions from the link 1 . download the . zip file 2 . rename from . zip to . hwt 3 . move to hwthemes folder in internal storage or sdcard
