You absolutely have the 3 I would recommend in CSUN, CSULB and UCLA.
My husband (bassist) attended CSUN, then transferred to CSULB after a year mainly because he had many gigs in OC area. He said it was a little challenging to break into the studio work near CSUN back then. He had the privilege of studying with John Clayton. 
Excellent programs and he had the opportunity to take production and engineering classes. Many/most of the current faculty are very active in the industry.
You might also look at CSULA. Our oldest kid (classical violinist) took a jazz class there last year and we attended a recital. Looks like a very good department.
We know a fair number of current students/recent grads at CSULB. They seem well trained and speak highly of the program. And they are getting good work.
Good luck!
