This Pack of 3 Artist Quality Mango Grip Guitar Picks is recommended for acoustic and acoustic electric guitar. These picks feature a thumb impression and finger groove to give you the best grip of your life. 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 provides 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".
