Active pickups are typically used in electric guitars, and they are often found in high-end models. Some of the most popular brands of active pickups include EMG, Seymour Duncan, and DiMarzio.
There are two main types of active pickups: single-coil and humbucker. Single-coil pickups are made with a single coil of wire, while humbucker pickups are made with two coils of wire that are wired in opposite directions. This helps to cancel out hum, which is a type of noise that can be caused by electrical interference.
Active pickups can be a great choice for guitarists who are looking for a powerful, clear, and noiseless sound. They are particularly well-suited for playing heavy rock, metal, and other genres of music that require a lot of distortion.
