A fairly good tone, and made by selmer - probably the worlds best saxophone maunfacturer
Lacking something that other selmers has, and I find some of the keywork is not in the best position - especially the palm keys! Also more expensive than the Serie II, which most saxophonists prefer to the serie III! (*)
A good sax, easy to play with good intonation, and a good keywork design. Also looks extremely cool! - i wish i could get my selmer in this finish!
It lacks the depth of tone found in most professional saxes, and it is also quite expensive - if you've got this amount to spend on a sax I would definitely reccomend a selmer instead of a keilwerth. (*)
