Now available for 5 string configurations! Cap dimensions (inches): Neck - 0.725´´ x 3.97, Bridge - 0.725 x 4.1´´. With sweeping harmonic overtones and clarity, the J pickup has characteristic jazz bass tone, but due to our custom design adds a modern broad tonal response that will add new dimensions to your bass playing. Our design has a very low ratio of resistance to inductance, which increases low frequency response, while the radiused ceramic bar magnet endows the tone with tight mid-range punch and dynamic high end response, all with less noise and more signal. So whether you play fretted or fretless bass, playing live or in the studio, you´ll get an incredible full sound to get the job done.
