I am a JK dissenter, just not a hostile one. I just never played one that I thought was better than the Selmers, Yanis, Yamahas, etc. Doesn't mean I think they suck. Who knows, I'll keep trying a few when I can and maybe find one that works for me. I understand they have quite the loyal following by certain people. Play what you like! :)

keilwerths are very very nice horns.. the ex and sx models i feeeell.. are comperably the same except for some noticable craftmanship differences. BUT! .. i feel that keilwerths are only good for people with large and powerful diaphrams.. which is pretty much essential for any sax playing but keilwerths have a significantly larger bow, and bell.. and they just seem bigger in general.. so u need to fill that horn with air.. but when u do, the sound is amazing.. looking back i sometimes wish i got the ex 90 i tried.. but i still like my yani
