A single-coil is a type of electric guitar pickup that uses a single coil of wire to convert string vibrations into an electrical signal. This design is known for producing a bright, clear tone with a pronounced high end, making it popular in genres like rock, blues, and country. Single-coil pickups are often found in guitars like the Fender Stratocaster and Fender Telecaster. While they offer a distinctive sound, they can be more susceptible to electromagnetic interference, which may result in unwanted noise or hum during performance.
