Jargar have a solid steel core and are very bright in tone. The A and D are a poplar choice often used with G and C strings of another brand.
New Special and Superior A and D are updated, and offer more power and soloistic projection than the original strings. Special is a slightly more powerful string taking more bow pressure, and Superior is even farther in the solo direction of tone and response.
