scratchplate

The scratchplate, also known as a pickguard, is a piece of plastic or other material attached to the body of a stringed instrument, most commonly a guitar. Its primary purpose is to protect the instrument's finish from scratches caused by the plectrum (pick) or fingernails during playing. Guitars often feature a distinct visual element due to the variety of shapes, colors, and materials used for scratchplates.

Historically, early guitars often lacked scratchplates, and players developed techniques to avoid damaging the wood. However, as guitar playing techniques evolved and amplified instruments became more prevalent, the need for protection became more apparent. The scratchplate also contributes to the overall aesthetic of the instrument, and custom designs and colors are popular among guitarists.

In some electric guitars, the scratchplate also serves a functional role by housing electronic components such as pickups, potentiometers, and switches. This integrated design simplifies assembly and can contribute to shielding the electronics from interference. The material of the scratchplate can subtly influence the instrument's sound, though this effect is generally considered minor compared to other factors like wood type and pickup construction. Materials commonly used include celluloid, acrylic, and various plastics.
