This Pack of 3 Artist Quality Tamarind Jazz Guitar Picks is recommended for acoustic and electric guitar. These picks are the classic Jazz III shape giving you complete control of your picking. Our Tamarind is a dense and medium grained wood of dark and milk chocolate browns and beautiful patterns. Tamarind produces rich tones and is very durable, making it a solid wood for electric guitar. Acoustic guitar players will notice a brighter overall sound without sacrificing the mellow tones so important in acoustic guitar. Tamarind trees have a rich history throughout the ancient and modern world and they are considered lucky. 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".
