Rotosound RS665LD Roundwound Swing 5-String Bass Guitar Stringsstar rating 4RobMarch 6, 2010I've tried this strings on my bass as I needed some thicker strings when we tuned down to drop C. I had to buy a 5-strings set and use the four thickest strings. Now I get the right kind of feeling when I play. Theese strings has worked fine for this metal genre I play.
