THOSE ARE THE ONLY SIZE PICKUPS FOR A MEXICO STANDARD JAZZ BASS. This new addition differs in that it uses Alnico V magnets instead of the ceramic magnets of the original. Because the JA utilizes Alnico V magnets coupled with short, squat coils, the tone is endowed with openness and warmth for a more vintage tone, all with less noise and more signal. We have no doubt that the new JA, with its natural presence, powerful lows, expansive midrange, and superior definition, will be as successful as its predecessor.Package Includes: EMG's exclusive Quik-Connect cables (2), prewired control set including 2 volume controls, master tone control, output jack, battery clip, and adjustment screws. So please do not be concerned if you see that. This form of tracking does not update every step of the way.
