Obligato B5 for bass

Pirastro's popular Obligato strings have a solid synthetic core with a very thin metal wrap. They were designed to emulate gut strings, and they did a darn good job of creating such a string. Their attack is "old school" with that more blunt and thicker, warmer hit, with a little less sustain than more modern jazz strings. Their very smooth surface is kind to the fingers and they are a dream to bow. If you want your sound to be "traditional", whether for bluegrass, old school jazz and blues, or other styles that calls for that sound, you will enjoy the Obligatos.
