As one of the greatest riff masters of all time, James Hetfield requires gear that functions as monstrously as he does – including picks. When he approached Dunlop to select a pick that met his high standards, Dunlop worked closely with him to develop a solution that not only kept up with his performance but enhanced it.

Dunlop used the Flow Standard Pick 1.0 mm as a starting point. The thrash titan put it through a series of tests on the road and returned to Dunlop with the improvements and adjustments he needed to get it just right. Initially, Dunlop incorporated the mixed, beveled edges of the Black Fang Picks for a super-fast attack that rings with bright articulation, ensuring that every note and chord has an impact amidst all that speed and amplification. Next, Dunlop made it slightly heavier, moving to 1.14 mm – typically not available in the standard Flow pick line – for the perfect balance between mass and articulation. Finally, Dunlop enhanced the grip by creating a custom pattern to keep the pick in place while Hetfield plays.

"The White Fang Pick has an amazing grip when sweating through heavy riffing and a smaller profile for faster playing," he says. "Plus, the white is easier to see when thrown into the crowd."
