I heard that you could use they're "dolce" strings in both solo and orchestral tunings. anyone know anything bout them?

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!
