This Pack of 3 Artist Quality Sonokeling Jazz Guitar Picks is recommended for acoustic and electric guitar. These picks are the classic Jazz III shape giving you complete control of your picking. Our Sonokeling is a rich red and dark brown wood and is polished to a bright lustrous finish. Sonokeling is a hard wood that is prized for its deep tonal qualities and for its natural beauty. Sonokeling is a type of Rosewood and therefore creates a clean, mellow sound while boosting modulation on acoustic guitars while rounding out tones on Electric. Sonokeling is durable enough to play with Electric Guitar while bringing out bright, accurate tone. Acoustic Guitar players will notice a bright, rich tone. Sonokeling is a popular choice for Guitar necks and is an excellent wood for any musical use. 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".
