Hi all, I'm looking to get valve alignments done on my horns. I was trying to contact someone at Yamaha Artist Services in NYC, but haven't gotten a reply back yet. My questions are: 1) Has anyone ever had service done at Yamaha Artist Serivces and how best to contact them? 2) What other reputable places are there to have my valves aligned or inspected in the NYC/Northern NJ area? 3) How much does it cost to have a typical valve alignment done. Thanks so much for your time! I would love to send my horns out to Bob Reeves in California, but with all the gigs at the moment, I don't want to be without my horns and would rather do something local. Thanks again!
