Click here to see the demo X Series, Active 4-String Pickup Set, Jazz Bass, Black. The JX provides increased headroom giving the voicing an open tone while still maintaining the clarity and response that EMG’s are renowned for. Featuring ceramic magnets and powered by a newly designed preamp, The JX pickup has characteristic jazz bass tone, but due to our custom radiused ceramic bar magnet, and the very low ratio of resistance to inductance, the tone has a modern, tight mid-range punch, and superior 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. Give it a try and experience why the "X" factor is exciting players all around the world. Package Includes: EMG's exclusive Solderless Install System (Patent pending); control set including 2 volume controls, master active tone control, output jack, battery clip, and adjustment screws.
