PRS 12-String sets are the specialized custom gauges used on PRS 12-String guitars from Paul's original shop and Private Stock. These gauges are as light as possible so the instrument plays like a six-string without sacrificing tone and overly stressing the neck. Nickel wound with brass ball end. Ships stock on PRS 12-String models. .010, .013, .017, .026w, .036w, .046w .010, .013, .009, .012, .017, .022w
