Pirastro Bass Rosin Medium

Pirastro Bass Rosin is an opaque yellow soft rosin with good grip. Pirastro developed this style of rosin for double basses so its texture and lightness will complement your instrument's natural sound.

Pirastro Flexocor Double Bass Strings, are the strings that Pirastro replaced the Original Flexocor strings with, in 1992. They are great Orchestral tuning strings (G D A E) and available as single strings or as in sets of four in all sizes from 4/4 to 1/16. Pirastro also makes a solo tuning version (A E B F#). The orchestral tuning Flexocor’s are the most popular and they are predominantly an arco string with a steel rope core…

The core material of Flexocor strings is a high-tensile rope made from carbon steel which is wound with chrome steel. They make a great arco string with a quick response and produce the typical warm sound of the orchestra with a short sustain.

Flexocor bass strings have a very quick response, are instantly playable and absolutely stable.
