Anthony has twice helped extract the mouthpiece from my son's trumpet that neither his middle-school band teacher nor the local music store could do. He did it in a matter of seconds and did not take any payment while the local music store damaged the paint on the lip without being able to extract the mouthpiece and then tried to sell us a new instrument! I just hope my son keeps up his interest in jazz so we can at some point in the future pay Anthony for his expert services! :)
