Single coil

Single coil pickups come from the early 20th century and are the first means of amplifying a guitar without a microphone. They are commonly found on the Fender Stratocaster and Telecaster guitars.

The single coil can be quite noisy and can create some heavy feedback. Certain guitarists are very talented in riding the wave of noise and manipulating it to create the sounds they are after.
