I just picked up an Ibanez SR305 5-string fretless in pearl white. It's missing a string, so I need to get some replacements. What are good strings to put on this? Flats? Rounds? Would prefer a brand that keeps the B string fairly tight. Thanks, MX Edit: not sure if this should go in "Basses" or "Strings", so if it's in the wrong place, mods please move.
