This is a Bach trumpet 180MLGP gold plate. I bought it new one year ago. My teacher, who is the principal trumpet player in a professional orchestra I'm studying with, had D musical instrument store order both an Artisan GP and this one from Nonaka for me to select from. I was told that the 180MLGP hasn't been in stock at Nonaka for the past few years. The tone is considerably brighter than a standard gold-plated finish. I'm selling it because it has less resistance and the blowing feel is not satisfying for me. It is a used item, so please refrain from purchasing if you are sensitive to such things.
