This Trilogy of 3 Jazz III picks is selected for use on ukulele, classical guitar and other fretted instruments requiring a softer strength pick and offers a variety of tone. These picks are the classic Jazz III shape giving you complete control of your picking. This Trilogy features the US Blues® Signature "Arc of Tone" from the following three materials: Coconut, Teak & Mango. Each is selected to offer excellent feel and tone and are also beautiful with varying grains, vibrant colors and feel great between your fingers. Coconut is a particularly strong material making it great for plucking. 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".
