Manufacturer's Description

Gauges 22-27-47-67-87-107-128.

SR2000 is the ultimate bass string built in the same manner as piano strings (no winding 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.
