"The Type 4 JB4-N is a 'short' sized Jazz bass pickup intended for the neck position on 4-string Jazz basses. These utilize 1/4&amp;quot; Alnico V magnet's and are built by hand to provide the highest quality available for Jazz bass.Tonally these are different than the Type 1, and Type 2's, Type 3's as they have a narrower field than the Type 4's and utilize larger pole pieces.This results in a more focused and articulate feel perfect for harmonics, tapping, slides, and capturing the nuance of fretless playing.This pickup is intended for 18.80mm spacing measured over the pickup.Please check the physical size of the pickups you want to replace to make sure the replacements fit properly.DimensionsLength = 3.60&amp;quot;(91mm) Width = 0.73&amp;quot;(19mm)Please Note:Aero does not provide screws with their pickups.
