The hardness of our gemstones will not absorb vibration and therefore allows the guitar to resonate longer. Thinner picks give you brighter sounds where thicker picks will not only be louder without any extra effort but also slightly lower and creamier. There are exceptions to everything and all of us know great players that could use any thickness and make the tone sound so fine. Come give us a visit and be amazed at the choices you have to choose from and be impressed with nature's contribution to our guitar sounds. Come see us at www.solidrockproducts.com Made in the USA.
