I’m just starting the course. Loving it so far, thanks Greg. I have been a 1.5C player for quite as will now. I play a lot of jazz and like the warm sound. I would also like to play lead however never been able to do it on a the shallower mouthpieces because I bottom out and get a double buzz thing happening. My question is, can I do the course on both the 1.5c and the Shilke 14a4a or should I stick to a mouthpiece which is middle of the road ie 3c.:)
