I have my Yamaha ytr 6320s which is my pride and joy, then i also have a King cleveland 600. The yamaha is the best horn i could afford and i like it a lot, it is easier to play nicely, through the register i have. Although i like the sound the King makes, it's warmer and mellower but quite hard to slot correctly in my high register. the Yamaha is easier to slot but sounds shriller and my low notes c down to F# sound almost like farts. (couldn't think of a better description sorry). Question is, i won't take my yamaha out to the park with me for fear of something happening to it so i take the King. Is it detremental to newer players to use 2 horns that are quite different? Should i stick strictly to my yamaha for a few more years? Or is it even possibly better to get good on different horns?
