Jargar strings are mostly known with violists and cellists.
They're made in Denmark.
The company is quite small; about 16 or 17 employees.
The bass strings have a soft, gut-like tone.
However they had a problem about six months ago and stopped production completely. (some specialized workers in the string finishing stage left the company)
But I heard production could start again soon.
Better contact Chris Quinn (chris@quinnviolins.com) about this. He is better placed to answer this question.
Maybe Lemur Music (
www.lemur-music.com) (1-800-246-2277) has some left in stock.
Hope this helps!
