Pickups notably determine the sound of an electric bass or guitar. Musicians substantially discuss the advantages and disadvantages of different pickup models. If you have little knowledge on electronics, you’ll find pickups to be very complicated. But in terms of electronics, pickups are fairly easy to understand. The two types of pickups are the magnetic pickups and piezoelectric pickups. Magnetic pickups consist of magnets and coils and specifically work with steel strings only. If you want a pickup that can work with all types of strings, choose the piezoelectric pickups. It is difficult to have a comprehensive overview of pickups because there are too many of them available on the market. One of the most popular is Steve Vai and you can get Steve Vai pickups at Guitar Center.
