I'm looking for someone who works on mouthpieces to perfect a Selmer S80 C*. I know a gentleman on here by the name of Edward Zentera who used to do a lot of that kind of work but now his time schedule and other obligations has prohibited him from keeping up with the demands of his customers. This is my girlfriend's mouthpiece that she uses as a student of saxophone at the collegiate level; we are preparing for a recital in March and we have determined her mouthpiece is in dire need of work. Any suggestions for someone who can do the work would be deeply appreciated. Thanks in advance!
