• b-axis Jazz pickups series feature a new and unique fully encapsulated Alnico V exposed pole design, and yet they are still fully shielded like all our enclosed pickups. The cable is shielded as well. b-axis Jazz Bass® pickups are dual-inline hum-cancelling design for use in professional venues and studios. They are sweat-proof and won’t make nasty noises if you touch them.
  
  b-axis pickups are super punchy and bright, but also warm. They have outstanding articulation, attack, and harmonic response. Musicians who play jazz, rock, country, gospel, and hip-hop are already finding their voice in b-axis pickups.
  
  Available in balanced bridge and neck versions.
  
  Typically, Fender® American Standard or Deluxe V Jazz Bass® with a standard/original bridge will use the 19mm version.
  
  Fender® American Standard or Deluxe V Jazz Bass® with the upgraded/narrow bridge will use the 18mm version. 
  
  **With the above being said, PLEASE BE SURE to measure the string spacing at the bridge to ensure you order the correct version for your bass.
