I got my old King Cleveland cornet out tonight when I was practicing, just messing around. This thing has seen better days and several years back I had some work done on it to get rid of the worst of the dents and to make it playable again. (It should be noted that most of the damage was done by my cousin, the original owner, prior to my obtaining it.) Was it playable. Sure. Did it compromise my playing. Yep - not tremendously though, and compared to my valve aligned Schilke B6, the most overt difference was between G and high C - the Schilke stays open to the top, and the cornet closes up. Having said all of that, it was that King cornet in my hands when I was successfully battling for first chair in 8th grade against a kid playing a Bach Strad.
