This Pack of 3 Artist Quality Mango Jazz Guitar Picks is recommended for acoustic and acoustic electric guitar. These picks are the classic Jazz III shape giving you complete control of your picking. Our Mango is golden brown and honey with small pores and a spectrum of additional colors intermittently visible. Mango is a medium hard wood with the characteristics of a much softer wood, therefore it is appropriate for producing soft warm tones on acoustic and acoustic electric instruments. Mango produces a full and accurate tone while creating a rich mid range and providing a good grip. Mango is used in the manufacture of Ukuleles, furniture and beautiful handcrafted items as well. 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".
