Jackson Professional Concert 5 Bass Guitar with Khaler Bridge and EMG Pickups

Description

***Please read entire description and review all pictures.  Feel free to ask any questions***
Jackson Concert V Bass up for grabs. This bass looks, sounds and plays beautifully in my opinion.
The bass has excellent tone. The pickups in this sound have been upgraded to EMGs.  They sound great and are what I would want in this bass tone wise.
These particular Jackson basses in this time period are becoming much more rare and difficult to come by, especially with the Khaler Bridge.
In the rewiring of this bass to install the EMGS, the 4th knob on the bottom was unwired.  So I believe the wiring is wired as 1 volume for the bridge pickup, 1 volume for the neck pickup, and a tone knob.  Again, the 4th knob is unwired and does not do anything.  I included a picture of the wiring, but can send more pictures of this if you would like more details.
As you can see in the pictures, the backplate that covers the electronics is not included.
The bass plays well and functions well.  Visually there is a good amount wear to the bass.  It's got scratching in the finish and some dings on the body and headstock. In my humble opinion this adds some authenticity as a tried and true instrument, built to last. Again it plays and sounds great, but visually has some wear.
There is a slight crack in the headstock directly under the B-String tuner (see pictures, its pointed out).  This doesn't seem to affect how it plays or sounds, but in the interest of being transparent I needed to point this out.  I would think if you wanted to fill this in with glue or have it glued professionally to seal the crack that it would be a simple job.  But I am not an expert and don't want to do anything myself.
Case sold separately.
