Dean Markley SR2000 Stainless Steel Bass Guitar Strings 6 String Set, 27-127 Medium Custom 6 String Bass Guitar, Silky Smooth Ba

SR2000 is the ultimate bass string built in the same manner as piano strings (no windings over the bridge) so the string has total freedom to vibrate. This special winding produces a string with the widest variance of tone of any string made. SR2000 has been the secret weapon of session players for years.
