Hi all, Just wondering if anyone has had any work on their horns done at Yamaha Artist Services in NYC. What services do they do there? Do they do Valve Alignments? Can anyone go there or is it just limited to Yamaha artists? I'm no Artist, but I do make some money from trumpet playing and just want to know about the facilty. I know that Wayne Tanabe and Bob Malone are there from time to time and that they are some of the best in the business. Thanks for your replies!
