Material: Almondwood, Bloodwood, Macassar Ebony & Thai Sindora. Instrument: We recommend Laser Tones Grip for both Acoustic and Electric Guitar. Tone: Thai Sindora and Almondwood 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. Macassar Ebony and Bloodwood 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. Design: Laser Tones Grip 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 grip pattern etched with a laser on one side of the plectrum to give you an unbeaten grip. Contents: This tin contains 1 of each of the Laser Tones Grip Guitar Picks.
