Well, Conns are supposed to have a HUGE sound. I mean, I don't know if I could ever play my Zephyr for classical, no matter what mouthpiece or reed I stuck on it. It just doesn't seem to have a sound that would work for classical. I mean, if I plunk down a bunch of cash and buy everything possible to darken and quieten its sound up, well...maybe then it would work. But I'm not positive.
And I read this in the vintage saxophones article on this site, which suggests that maybe a Conn is a bad idea for other styles of music. Could just be the mouthpiece choice, though, I suppose.
"Big Band Music, Full Sound
Conn 6/10/12M. Best years/finish/mouthpiece: early 1940's. Lacquer. Otto Link mouthpiece.
Advantages: big sound with this setup. Rolled tone holes to "prolong pad life." Connqueror (26/30M) models available as a step up. Very popular.
Disadvantages: IMO, a boomy sound that's hard to control. Somewhat hard to keep in tune. If body tube is damaged, tone holes are difficult to repair (or, it's difficult to find a repairman that's worked with them). "Vintage" keywork. Can be expensive for good examples ($2000+).
Runner up: Conn New Wonder ("Chu Berry")"
I'm just wondering

Any thoughts?
