I've watched the Video, and still prefer my Bari Esprit mouthpiece collection costing just £42 inc. shipping for soprano, alto and tenor mouthpieces!
Are you implying that he has made good mouthpiece choices, or simply has had them all from beginning to play the sax and never thought of improving his sound by trying/buying any other mouthpieces?
As he started playing sax when 13yo (1974ish) then many mouthpieces were not that available in the UK, or even developed at the time, and people just played what they could get hold of or were given, without question, especially as he was from oop north.
Sadly, I have bought several mouthpieces over the time that I have been playing before watching the video. At the same time I am pleased to have contributed financially to the saxophone community by so doing, so that shops and craftsmen can continue to earn a living!
Thanks for the Original Post!
Kind regards
Tom
