Picks, also known as plectrums, have been used on musical string instruments as far back as ancient Egypt. Many musicians use picks to change the way the music sounds. The thickness, shape and material of the plectrum all contribute to the overall tone the strings produce. Although most modern picks are made of celluloid, many other materials are used such as bone, wood and even metal! Now, for the frst time ever, musicians can make their own sound even more unique with an authentic silver Fender® guitar pick!
