The RCG BassOhm is essentially two unique single coil pickups. One lean coil based on the ?52 P and one fat coil for a thicker, deeper tone. This pickup is designed to be paired with a 4-way blade switch for maximum versatility, but can be used with a mini-toggle for two or three of its voices or no switch if you have one favorite. When used together, the coils are hum-cancelling. 53mm string spacing. Chrome, Nickel, or Gold open covers are included, wooden covers are available on request.
