The Jazzer ropecore steel strings are recommended by Pirastro for pizzicato players, though they can also be a good hybrid string for players who gig many styles. I've not had the opportunity to play a set in quite a while, so I'll pass on their comments:
- for the Jazz musician
- clear, powerful sound
- big tonal volume
- unexceeded ability of modulation
- long sustain
They offer them in 3/4 size and at one gauge only, Medium. Color codes are as follows: (headstock/tailpiece) High C=violet/rose, G=brown/red, D=red/blue, A=black/green, E=green/orange, Low B=yellow/d'red, Extended E=green/orange.
