A good, level fingerboard is important, you can't compensate for a small high spot by scraping down a fret.
 
	 
 
	If it has side dots, be sure they are where you want them. On some (mostly defretted) basses they are between fret positions. I learned on a bass with dots at the fret positions and trying to play with the other style is tough as they 'draw' my fingers away from proper intonation.
