I must provide this disclaimer. I endorse this horn professionally. However, I am 100% sincere in all my comments. This is, without a doubt, one of the finest horns I've ever played. It has the best valves I have ever had. It plays in tune with a wodnerfully flexible and expressive tone. I find it works beautifully in all idiom from classical to screaming jazz. The Stage 1 Califorina is also a solidly built horn. You won't feel the need to baby it or mollycoddle it. It is a fantastic tool for any trumpet musicians toolbox! I can't reccomend it highly enough. It is also favorably priced for a pro custom horn.
