Larry,
I think that a well made horn (Bach, Calicchio, Schilke, Scodwell, Lawler ...) provided you balance it well with the right mpc with the right player it's what's important. Examples:Charley Davis (Bach) Ingram (Schilke) Findley & Trigg (Calicchio) Tony Scodwell & host of other in Las Vegas (Scodwell) Charlie Berrtini in Orlando FL (Lawler).
I really have to say that Calicchio trumpets do lend them selves towards a very nice sounding commercial sound, with an extreme ease of playing! No doubt there !!!
Has there been any talk about the "Chuck Findley" Calicchio?
As far as what has helped with my usable range ... striving to be an "efficient player". (edited for continuity)
I think the key is making wise choices ... pick the right tool for the right job!
