The original EMG J 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. Packge includes: EMG'S EXCLUSIVE SOLDERLESS INSTALL SYSTEM: 2 25K VOLUME POT; 1 25K TONE POT; 1 BATTERY BUS; 1 STEREO OUTPUT JACK; 4 PAIR MOUNTING SCREWS; 2 PICKUP CABLES; 2 CONNECT CABLES; 1 OUTPUT CABLE; 1 BATTERY CABLE.
