D'Addario Jazz Light Gauge # Half Round Strings Jazz Light set EHR350, half-round electric guitar strings with polished stainless steel wound strings. They achieve the bright sound of round wound strings and the smooth string touch of flat wound strings. The feel and tone are like a hybrid of round wound and flat wound, which is appealing. #D'Addario #Electric Guitar Strings Purchased at Soundhouse.
