This Pack of 3 Artist Quality Teak Guitar Picks is recommended for acoustic guitar. Our Teak is light brown and amber with grains of dark brown and small, grippy pores. Teak is a softer wood that is known for being durable and impervious to changing conditions in moisture and humidity; therefore it performs well under many playing styles and wears in beautifully. Teak produces a full rich tone while providing a soft but accurate attack allowing players to dance along the strings with a fluidity not possible with a substantially harder pick. 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".
