First make sure the neck is straight, then lower the strings until they buzz a little, then raise them back up just until don't. Now you can check the intonation-harmonic on the 12th and/or the 19th fret should match the fretted note. The bridge should be about a half inch or so behind the pick-up. I like to put a little bit of double back tape under it to hold it there. Good luck and have fun. That should be a delightfull bass.
