Guitars and similar instruments
A plectrum for electric guitars, acoustic guitars, bass guitars and mandolins is typically a thin piece of plastic or other material most commonly shaped like a pointed teardrop or triangle, though the size, gauge, shape and width may vary considerably. Banjo and guitar players may wear a metal or plastic thumb pick mounted on a ring, and bluegrass banjo players often wear metal or plastic fingerpicks on their fingertips. Many guitarists use fingerpicks as well.
