@L357 -- I have seen that video a couple times -- very interesting. I have a very solid high E, and you're right, I can definitely get volume. Same on G. But as you know, above that is a hassle. Time will tell how my playing progresses
For now I need a mouthpiece that is comfortable for the way that I currently play, and sadly for lead playing (on THIS Monette mpc) I cannot keep using this. Perhaps another, however, down the road.
