Pickups, one of the core components of Heilongjiang electric guitars, are used to collect the vibration of the strings and convert them into analog signals (electrical signals) for output. Electric guitars generally have 1 to 3 pickups. Common pickups include single coil and double coil (Humbucker). The position of the pickup on the body is generally used to describe the pickup: the one near the neck is called the neck The pickup (Neck), which is near the bridge, is called the bridge pickup (Bridge), if it is a 3 pickup configuration, it is called the middle pickup (Mid).

The pickups on electric guitars can be classified into active pickups and passive pickups according to their working methods. The passive pickups were invented in 1924 and the active pickups were invented in 1976. Or classified into single-coil pickups and double-coil pickups according to the coil structure. The earliest pickups were single-coil pickups. In order to solve the noise problem caused by the single-coil design at that time, the double-coil pickups were invented in the 1950s. The signal converted and output by the pickup still has to be processed by the electric guitar circuit before the final output. In common sense, the sound of a single-coil pickup is "bright" and "thin"; the sound of a dual-coil pickup is "dark" and "thick". The position of the pickup on the piano body also affects the picked-up sound. The closer to the neck, the darker and thicker the sound. On the contrary, the closer to the bridge, the brighter and thinner the sound.

The pickup consists of a conductor coil, a number of magnets (generally equal to or twice the number of strings) surrounded by the coil, and a frame to fix these parts. By surrounding the magnet with the coil, the pickup can form a stable magnetic field. The magnetic field magnetizes the metal string. The string itself also generates a magnetic field. The magnetic field generated by the string moves with the vibration of the string, causing the magnetic flux in the coil to continuously change, which is generated according to the principle of electromagnetic induction. Corresponding to changing electromotive force. The material of the pickup magnet and coil, the number of turns of the coil, the distance between the magnet and the string, the winding method of the coil, and the material and style of the structure will all affect the tone of the pickup.
