Had problems with 5335gsii monel valves eventually middle one sticks, Yamaha uk could not be bothered to investigate what the problem was so put us off this brand, replaced a previous new trumpet that had black circle mark inside the valve right out of the box. Sent away to their workshop for 5 months but came back with same problem despite one valve being lapped, dreadful experience.
I will be a Yamaha artist one day.
This one of the reasons that I play Yamaha trumpets
