These strings generate a lot of requests, and I can say that they are popular among jazz players who want a little more brightness and a smoother bowing surface out of their gut strings. A more "traditional" wound gut string would be the Olivs, also from Pirastro.
All strings are gut which is wrapped in a flat silver tape for more sustain and smoothness.
Pirastro says: The gut string!
- excellent bass string for orchestra and Jazz bassists
- excellent & brilliant sound
- high ability of modulation
- long sustain
- fits perfectly for Arco and Pizz
