The ACB-5 banjo pickup is the the choice of pro players due to its authentic recreation of the instrument's natural tone and low noise. This pickup allows players the ability to hear the banjo amplified without giving up any of the tone they love. The EMG ACB uses a dual-coil Alnico magnet design. The pole pieces compensate for an even string balance for a variety of string gauges.This innovative design has the coils spaced apart from one another creating acoustic “chambers”. These gaps allow sound waves inside the banjo to resonate around the coil walls that add acoustic quality that has not been achieved in a magnetic pickup until now. Whether recording or performing live, the ACB produces a true banjo tone that is noise free.Make sure to check the instructions for pickup measurements before purchasing to compare your existing pickups with EMG models.
