Cort Bass Guitars

Active EQ circuits are able to both boost and cut certain frequencies. Most tone controls just cut the treble frequencies of the signal but these do both and are often designated as separate controls for treble, middle and bass. This means you can have a lot more control over your sound: you can sculpt frequencies more specifically in order to get the exact sound you want. These circuits are called 'active' because they require extra power to make them work. The power comes from a 9V PP3 battery, located in a compartment on the back of the instrument.
