There, um, is, um, no such thing, as, um, too much.

The point really is to get instruments, pedals and amphs that you love and enjoy playing. If they are paid for and not in the way around the house too much then keep them and play them when you feel like it. I absolutely love going into my closet and pulling out 4 or 5 guitars that I haven't played in a year. I really appreciate what I have, am glad that I got it don't feel the urge to go out and buy it because I've already have it.

But if your house starts looking like an episode of Hoarders then you might want to seek professional help.
