MATERIAL: 1.00mm thick. Manufactured from Aerospace quality Carbon Fibre with a high gloss finish on both sides.. SUITABLE FOR: We recommend Carbon Tones for both Acoustic & Electric Guitars.. TONE: Carbon Fibre is hard and dense and as such has clean crisp bright tones.. DESIGN DETAILS: Carbon Tones are designed around the Classic 351 shape. At 1.00mm thick these Guitar Picks have a medium level of rigidity. We use a CNC Water Jet cutter to cut out our unique shape to exact tolerances. They are then hand polished around the edges to ensure they are perfectly smooth.. CONTENTS: This pack contains 1 Hard On Carbon Tones Guitar Pick.
