I just recently purchased a set of these for my acoustic guitar. Thomastik KF110 S Series Classical Light Flatwound Strings http://www.amazon.com/Thomastik-KF110-Series-Classical-Light/dp/B001633C0K/ref=pd_sim_MI_1 I really love them. They're lower in tension than regular guitar strings, they have a sound that's somewhere between a steel-string guitar and a classical guitar, they have virtually no finger noise (compared to regular strings), they're long lasting and save you a lot of money (despite costing more than regular strings upfront) and I don't have to worry about maintaining figner callouses as much (I'm mainly a bass player, so I don't play guitar as often). As far as I'm concerned, these strings are a bass player's best friend. Has anybody else on here tried them? If so, what are your thoughts on them?
