Herco Vintage '66 Light Gauge Guitar Pick - Gold (6-Pack) The Herco nylon pick was the top choice of guitar players when guitar-driven music began its meteoric rise in the mid-1960s. Dunlop is bringing back that pick's classic tone and feel with the Herco Vintage '66 Series. Digging deep into our vault, we carefully analyzed our collection of original Herco molds and picks from the 1960s. This enabled us to create the Vintage '66 Series to such exacting specification that even our pick experts were at a loss to tell them apart from the originals
