Re: too nice to play - playing ultra high end JEMs?
I agree with the above, I don't own anything as rare as those Jems listed, but I am reluctant to take my most expensive guitar to live gigs. My main gigging guitar (a 550) is covered in nicks and dents and I consider myself to be pretty careful with it, these things just happen when you're moving equipment around a lot. Besides, your equipment is not always in your own hands.
At home though, I'll play anything I feel like. I can't understand why a player would buy a guitar and never use it, no matter how rare/valuable it is.
