This Trilogy of 3 Finely Sculpted TriStar picks is selected for use on electric guitar and electric bass and other fretted instruments requiring a hard or very hard pick. These picks are finely sculpted jumbo triangle shaped with 3 identical picking points and a grip hole cut clear through the center allowing a super firm grip. This Trilogy features the US Blues® Signature "Arc of Tone" from the following three materials: Ebony, Rosewood & Padauk. Each is selected to offer excellent tone and response and are also beautiful with varying grains, vibrant colors and feel great between your fingers. Trilogy samplers bring an "Arc of Tone" to your playing. US Blues® offers music accessories made of sustainably sourced exotic materials that improve the tone and modulation of your instrument and therefore your overall playing and enjoyment. We use by-products of various industries, such as guitar making, to source materials that otherwise would not have been repurposed. We strive to bring the quality of your music to a new higher level and are proud to have elevated the guitar pick to the level of "Pick as Instrument".
