These strings changed my outlook on playing my acoustic guitar. I have been searching for a while to try to find acoustic strings at a good price that felt more like electric strings. Sure, electric strings would work on an acoustic. But just didn't have that same richness to them. Tried several different gauges with the same outcome each time. Then I heard of the Earthwood Silk and Steel strings. Put them on and just tuning it I could tell a difference. Have that warm rich acoustic tone. But don't make your fingers feel like you put them through a grinder after playing for a half hour or so.
