Michael,
It has to be said that I usually prefer darker pieces but in a modern fusion/rock setting I think this mouthpiece is very hard to beat. It responds extremely well throughout the range of the horn and has bags of projection. To my mind it's similar in tone to a JJ DV but less expensive of course. In fact, the weak Dollar rate makes Morgans incredible value at the moment for players in the U.K.
I like the feel of ebonite pieces and the Morgan is very comfortable indeed. The outer profile and beak angle are the same as my Meyer alto piece, so when I'm going between alto and tenor it requires no difference in embouchure whatsoever.
I'd like to try an L chamber, so may order one of those soon from JunkDude...
