I would like to tell you all of my dealings with this nice guy who refaced a mouthpiece for me. I was given a quite badly damaged Otto Link Master mouthpiece. The rail had been knocked in and it was unplayable. Well the search was on for a refacer, as Ed Zentera was not taking any refaces at the time. I read posts on this forum and chose to send it to John. The result is better than I could ever have expected. He does not have a high profile and maybe it is as he chooses, but he certainly does the job. So thank you John Rielly I am so pleased, in every way with the mouthpiece you salvaged for me.
