A pick that may have: a first layer or core that is configured with a first color; a second layer or coating configured with a second color; and, wherein said second color visually contrasts with the first color. Operably, the coating or second layer may be abraded whenever the pick is used to flick a guitar string whereby the coating or second layer erodes to expose the first color of the core or first layer. A musician may identify that the pick is worn out via seeing the first color showing through from underneath the coating or second layers. |
