Since the bass is such a horrible disaster. .Sell it me for $500... I'll play the heck out of it and it will look alot worse in one years time!.

What are you doing inspecting the bass with a microscope eye anyway? You should be Playing the thing.. If it sounds great. Thats all that matters. They are To be played not worshiped!
Just sayin.
PS... the neck is NOT cracked. It is a small finish / hairline fault that happens to almost all boltons that have a Nice Secure neck.. You want that tight secure neck... Someone said it happens when the neck Pocket is Too Tight>. Its exactly what you want. you want the Neck pocket to be that tight. Its not a fault that it is too tight.. Its part of making the bass correctly... Thats what allows the neck and body to resonate together as much as possible....
Sadowsky uses a Thin finish which is what you want. It's already a POLY finish, so the thinner the better for tone.. Some of the Thick fender finishes smother the wood
Your Fenders dont have that happen because 1) the fender's finish is as thick as road pavement.. and 2) the neck pocket is most likely Loosey Goosey because it has a pocket and is just a "Close enough for mass production spec." bang them out and get it out the door thing..
Nothing wrong with your bass, Turn it at another angle and you probably wont see it. Just play the thing and get your groove tight...
