This Pack of 3 Artist Quality Padauk Sculpted Heart Guitar Picks is recommended for acoustic and acoustic-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. Our Padauk is a fiery red and dark brown wood and is polished to a bright matte finish with a deep grain excellent for attaining a firm grip. Padauk is a medium hard wood that is prized for its deep tonal qualities such that it is used for xylophones and marimba keys. Padauk is sometimes compared to Rosewood and therefore creates a clean, mellow sound while boosting modulation on acoustic guitars and rounding out tones on electric. Padauk is an excellent choice for those seeking a grippier pick and who demand a rich fully developed sound. 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".
