EM Winston quality is spotty at best! I have owned two "ProI" models in the past: A Silver Plated Soprano, and a Black Nickle Plated Alto. The soprano was good (in tune and sounded decent enough, owned it from 1994 to 2008, many gigs, lots of road time) but the Alto was horrendous! Would NOT stay regulated, had burrs on the inside of the sax, squeeky keys, horrible intonation. Just a waste of money. Bought it in 1996, sold it in (at a huge loss, with very little play time on it) 2001.
Curious, what was the determining factor in the purchase, has quality at all improved this brand?
