The Weltklang Baritones are one of the best products which came out from this factory and are widely appreciated.
They are certainly not in the same category of some cheaper Weltklangs . The factory which as you know , made also B&S blue labels, had moments in which especially the alto production was really of low standards but this didn’t affect all their saxophones.
The latest of their Sopranos and the Baritones certainly belong to their best production.
I have owned one Weltklang Baritone and one B&S Blue label. Both had low A. Weltklang had a very special key arrangement for which the Low A was reached both with a key by the thumbrest and with another key on the left hand plateau.
The quality of the sound is good and powerful, also intonation (with quirks not unlike any instrument). You can buy one for €1500. Personally I’d rather invest in a Weltklang low A baritone than in most Chinese brands. If you are looking for a relatively low price Bari, think of Jupiter too.
