Gauge .030, Stainless Steel Wound - Electric These are the same guitar strings Rogue uses in prepackaged retail sets. What"s the difference? We package 12 strings of the same gauge in airtight vinyl bags with a packet of silica gel to protect against unwanted moisture, so they last longer than typical string sets. We also pack these bulk strings in big, loose coils to avoid compressing or stretching the windings, so they sound better than tightly coiled strings. Rogue Strings are made exclusively for us by a famous manufacturer, employing the finest materials and the latest manufacturing methods.12-Pack Stainless Steel strings Gauge .030
