Material: African Ebony, LignumVitae, Ironwood & Burma Padauk. Instrument: We recommend Laser Tones for Acoustic Guitar and Electric Guitar. Tone: African Ebony & Lignum Vitae are two of hardest Timbers that we use and have very clear clean tones, which can help to add some brightness to the tone of most guitars. Burma Padauk & Ironwood are two of softest Timbers that we use and have very warm tones, which can help to add some warmth to the tone of most guitars. Design: Laser Tones are based upon the Classic 351 shape. They are typically 2.5mm thick chamfering down to a playing tip at 0.7mm thick. They then have a symbol etched with a laser on one side of the plectrum to give you a subtle grip feel. Contents: This tin contains 1 of each of the Laser Tones Guitar Picks. 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.
