If you are in the United States, particularly CA, just don’t give more than 2 weeks’ notice. You aren’t required to give any notice but it’s professional courtesy to give this much notice.

Make sure that your manager is willing to give you a good reference for your future gigs. If you suspect that that will not be the case, then just use the 2 weeks notice to tie up loose ends personally and getting some downtime before your next gig. The courtesy you extend to your boss is Not entirely free - your boss is also expected to extend professional courtesy by giving you a good reference, assuming you are not leaving because of performance issues or for cause.
