This Pack of 3 Artist Quality Buffalo Bone Jazz Guitar Picks is recommended for electric guitar. These picks are the classic Jazz III shape giving you complete control of your picking. These picks are an excellent replacement for real tortoise shell picks (which are illegal and not endorsed by US Blues®) in their beauty and luster. Bone and Horn picks are known for their hardness, full tone and regularity or consistency. Horn generally produces a softer more balanced tone while Bone is brighter, stronger and even harder wearing. These picks are among the hardest wearing in the entire line. 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".
