Available as a separate units, the LJX and SJX are the two pickups in our JX Set, the LJX usually located in the bridge position and the SJX located in the neck. The EMG JX Set is based off the original J with the added headroom and dynamic response of the X Series preamp. 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.
