This Pack of 3 Artist Quality Buffalo Black Horn TriStar Guitar Picks is recommended for electric bass and electric guitar. These picks feature a large jumbo triangle shape with 3 identical picking points and a grip hole cut clear through the center allowing a super firm grip. 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".
