I typcially play all my guitars...in part because I don't have much of a gear allowance so I don't buy stuff I won't play. But it's also part of my personality...can't justify keeping something I don't play.
The one exception is my MIM Fender Strat...I mostly keep it because it's worth more to me laying around than I could get if I sold it. Also, if one of my daughters decides she has interest in playing, it'd be a good starter guitar. And I do occasionally plug it in.
I had a beautiful semi-hollow Charvel Surfcaster with a Greenburst finish that I sold a couple years ago. That is one guitar I would have kept for it's looks, but it never quite got the tones I wanted and I needed the money to buy a Les Paul. I recently found it on e-Bay...someone is trying to get about 4 times what I sold it for (or paid for it in mint condition 10 years ago), but it's been up for weeks without any bites, I'll be surprised (and depressed!
) if he gets any takers at anywhere near that price. Here's a pic and the link:
