What pick thickness do you use? Most people seem to gravitate toward what is now a medium size (around .6-.8mm). At one time, picks had no standard thickness. They were essentially the thickness of whatever the material was available at hand. D’Andrea got into the pick business early one – in the 1920s and dominated guitar picks well into the 1970s and still makes picks today. They standardized many thicknesses of picks that are quite common today (.50mm, .60mm, .73mm, .88mm, 1.0mm, 1.14mm). That said, you can picks from Dunlop’s nylon .38mm up to 3.0mm in more esoteric materials like Lexan. Thinner picks (.60mm and less) seem to be used more in acoustic strumming. They provide a lighter touch (attack) with less clicking noise. Precision picking involved in soloing (and lighter string gauges) usually requires a harder pick – usually greater than 1.0mm thick. These same precision pickers tend to gravitate to the jazz shapes with a more aggressive grip on the pick.
