I'll just add that when the reeds are properly wet, my tone (personal opinion) is the best. Too dry and it's terrible. Some guys say they pick the sax up, give the reed a lick and play - others do it the other way and keep their reeds soaking like Nick, others buy a humidity controlled reed case that is supposed to keep them at optimal wetness... Im not a big fan of Vodka, but maybe I should try some whisky...
My tenor reeds live in a simlpe La Voz case, which lives in a tin, so the reeds dry out and take a bit of soaking before they're playable. The alto ones go in a Roco case, which is supposed to be humidity contolled, but I never bothered with the moisturiser packs. These usually come out slighlty damp, and seem to be playable quicker, so I guess there's something in it's favour.
