Marcel Mule did use a Selmer metal C* as did many classical players of that era ,,,however the sound that these pieces produce is a little dated ,,actually a trifle old fashioned ,,,,as for Hemke his metal is a Selmer true,,,,, but it has a square chamber as in the S80 chamber not round as in a Larry Teal ,,,but if you are looking for something different i suggest you give a Vandoren A17 a try ,,,,,DeLangle does wonders with it
