This Pack of 3 Artist Quality Buffalo Bone Sculpted Heart Guitar Picks is recommended for electric guitar. These picks are finely sculpted artisan crafted guitar picks with a double thumb impression and finger groove designed to provide a comfortable pick grip while also being crafted in the shape of a heart creating an attractive and beefy sized pick. 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".
