I recently was on musiciansfriend.com and I came across some strings made by Fender, they are flatwound strings wrapped in nylon! They seem pretty neat, but I don't know how useful they can be. Apparently they get rid of the metallic sound and last for a very long time...anyone know anything about them? I'm thinking of trying them out but I want to be careful...also does anyone know if a set of 5 is available? The set I saw was 4 but I have a 5 string. Thanks!
