Mmmm, I'm not sure what I'd class myself as.
I've been playing for about 25 years now and I have a few guitars. One is particularly great for blues and has a really unique look, so I've held onto it for those reasons, but when I am performing I'll stick with the one guitar my Fender California Fat Tele.
The decision to buy that originally was based on the feel of the neck, how it felt 'hanging' on me if I was comfortable or not with it, sound (I tried about 30 guitars out that day before I narrowed it down the Fat Tele) and versatility (because at the time I was in a covers band and needed to be able to play EVERY style and the tele was great for that).
Like we used to say, from Abba to Zappa.. we covered it all.
As far as amps go, it's usually been my old Peavey Special 160 watter. It's old, it's solid-state, has a 12 inch speaker but it can *just* keep up with a quadbox and decent head (I went up against a Soldano head once and I just about matched it and the quad-box it was paired with) - plus it just sounds great.
So that's been my amp mainstay, until now.. I recently bought a little 15watt Roland Cube.. the portable one. It's fantastic for the price and it's fun to try the amp simulations. I've even done a couple smallish gigs and jams with it and get stunned comments.
So I think more than having a big array of instruments, or the instruments themselves being versatile (altho that is certainly an option) it's important to keep yourself versatile.
Why hedge yourself into one little niche when there is so much out there to experience?
