I don't play out with mine. I just use them for songwriting, jammin and recording, so I picked what I feel are the two best basses to own if you can only justify two. I owned both of these models 25 years ago when I was running my own commercial recording studio, and they definitely complimented each other nicely.
So when I decided to get back into writing and recording, I wanted to get those two great bass models again.
With quality amps and outboard gear, you can get pretty much any bass sound you want out of these.
