The J5 Set is the original EMG J Set for 5 string bass. This set became an instant hit with its sweeping harmonic overtones, punch and quiet operation. This pickup set has classic jazz bass characteristics with a broader tonal frequency range that adds dimensions and clarity to your bass playing. EMG's design has a very low ratio of resistance to inductance, which increases the low end response, while the radiused ceramic bar magnet ensures the tone keeps a tight mid-range punch with dynamic high end response. Whether you play fretted or fretless, live or in the studio, you'll get an incredibly full sound with these bass pickups. Cap dimensions (inches): Neck - 0.725'' x 3.97" Bridge - 0.725" x 4.1''.
