well i recently purchased a Ric 4001 and i am trying to decide what kind of strings to put on it. i want something with a much darker sound than average steel rounds. i don't want flats either...so what're my options? i was looking at some of the coated strings like the D'addario EXP or Elixers. And i was greatly intrigued by the D'addario Half-Rounds. Any suggestions?
