Obligato Bass Strings
Before the Evah Pirazzis came out,
Pirastro's Obligato bass strings were the 'hybrid' bass
string of choice. For years, string companies tried to find a
string that upright bass players could be happy with for bowing as
well as a plucked string. Or, a synthetic bass string that
sounded exactly like a gut, but without all the hassles of using gut
or the higher prices of gut strings.
Obligatos are slightly different than the Evahs in that they have a
stiffer feel. They too have a synthetic string core and while this
gives the bass string a warmer tone with the bow, (even more so than
a Flexocor), the core also lends itself to being a good jazz or
plucking string because after the initial "pop" of the string, there
is a longer sustain. (Jazz players usually like this much

If you are new to the upright bass strings
market, the Evah Pirazzi bass strings and Obligatos
are almost identical, but the Evahs are even more flexible.
For bowing, the Evahs "turn" a little with the beginning of each bow

bass. See our
Evah Pirazzi bass strings page for additional information.
Lots of Jazz players are starting to ask for the Evah Pirazzi bass
strings, while the Obligatos may suit the classical player more for
their rigidity with the bow. Having said this (about Jazz
strings) the Evah Pirazzi strings were really developed for
Evah Pirazzi bass strings: softer, more sustain after the
initial "pop" (plucking) and even warmer sound with the bow.
Obligato Bass strings: more rigid core, slightly less
sustain after the "pop" for plucking, but with the bow, still have a
warm sound. Obligatos have a very slight advantage with the bow
response (and not as much turn or twist) of the string as with the
