hi Thomas, we purchased a YTS5335gsii but have had nothing but problems, stains inside the brass areas of the valves within weeks, replaced trumpet. After a few months the new trumpet had stains in the brass parts of the valves and middle valve sticking despite recommended cleaning. Can the Monel valve process be investigated, the surface is undermined with heat that may be the cause of the monel sticking, heat weakens the coating. The trumpet was returned to Yamaha worshop and they lapped the middle valve, without our permission and we are not happy. This was a new trumpet and it has given us nothing but problems. We had an old Boosey and Hawks that was better and more reliable than this, with nickel coated valves and looked forward to a brand new instrument from Yamaha. Sent to workshop in Feb it is now May 2020.

Like most of these videos, the information is really good, though it's presented with the feel of a bad 8th grade acting class.

@Malteboy777 I bet they could, but I doubt they could get anyone who can customize a trumpet better than this guy!
