Tone: Sugar Maple is a relatively soft Timber, which will add a good level of warmth to the tone of most Acoustic Guitars. Design: Timber Tones are CNC Milled from the very best quality timber then hand sanded and hand polished to give them their amazing shine and smoothness. Timber Tones unique shape is roughly based upon the classic 351 design, however they are 2.4mm thick where you hold them, chamfering down to 0.7mm at the playing tip.

Notes: Although we have tried to ensure that our photos represent the Guitar Pick that you will receive, there is a high level of variety in our picks due to the nature of many of our natural materials.
