Flats as in flat-wound strings. Is there really any reason to change them unless they break? I like the sound of flats, and I think it will a nice addition to a Stingray HxH to tame the growl just a bit...plus when I get it all set up with string height and such, the only thing that should need adjustment over time is the truss-rod, right? Theoretically that is. Am I crazy?
