You would be pretty hard pressed to get a decent return on investment with a bass, unless you got something very rare very cheap or you got lucky on some brand going crazy (sort of a Wal thing).
Maybe 20 years ago when a lot of things were unwanted it would have worked, but not now so much.
There are so many better options.
No, historically some particular year and model of certain brands have held their value, most haven't. Even your pre-cbs fender if you work out the price now to the equivalent price when bought haven't gained much.
No, if you want lots of basses, have loads of basses, if you want investments there are better places to look.
