They are made on Round cores with unique core-to-wrap ratios, so the gauges which match up with some of our standard sets are not the same at all!There are several advantages of using these strings. Vintage guitars, light braced guitars and people who have problems fretting due to arthritis or tendonitis can use these strings without worrying about twisting or uneven pulling on the bridge. Low tensions also mean ease of fretting.ATTENTION: Round core strings – Do NOT cut the strings until they are installed ans tuned to pitch!
