for some strange reason Brazil seems to be home to TWO makers (j'elle Steiner & Lopes) of all manners of Bass and Contrabass saxophones (this one being a " compact" subcontrabass ).
Why would anyone produce some of these horns capable of extremely low (and harmonically unpleasant sounding notes.......lower than D the other notes sound almost the same and I doubt anything remotely fast could ever be played ) is beyond my understanding.
I much prefer the way more expensive Eppelsheim instruments which are way better in terms of sound AND of mechanics.
The older style low saxophones were very nice too.
flutes too......
Anyway the super low sound is not limited to woodwinds
