Hey good folks of UG, so I've been playing guitar for 6 years now and I'm starting to get into jazz guitar. I was wondering how much of a necessity flat wound strings are for this style, by that I mean do most of the major jazz players use them, guys like John McLaughlin, Wes Montgomery, Charlie Christian, etc? How big of a factor do flat-wounds play into getting a good jazz tone? I currently use DR blue blues 10's, do flat-wounds take getting used too?

Thanks Guys

They take a lot of getting used to. Very different feel, duller tone, don't grip a pick or fingers well for right-hand work and for bending. On the other hand they're silky smooth, have a unique low thump, and last a long time. I would not call them necessary for a jazzy sound, those pure nickel strings are good enough for most purposes.

Only way to really know though is to try a set.
