For the past year, I have been using Hawk Picks exclusively. Rob Edney from Hawk Picks in Manchester UK, makes bespoke, handmade guitar and mandolin picks that are extremely hard-wearing, vastly outlasting regular, plastic picks.
Not only that, but they sound great, tonally. Seriously – Never underestimate the difference a good pick makes to your sound.
