As I said earlier, I do use my 'best' guitar when I'm gigging at a known venue, or taking part in sessions, etc. The only gigs I don't take it to are those where I don't know in advance what the environment will be like - there are a few pub gigs I've done where I was glad I had one of my older guitars (but as I say, I've never had any damage caused in such places).

(The other problem to overcome, related to that, is when someone asks to borrow your guitar, perhaps at a session, or at a private gig where Old Uncle Fred wants to play Wild Rover 'cos he always does at family gatherings, and he just wants to borrow your guitar for five minutes, then he beats the **** out of it. I wouldn't want to lend my good guitar to anyone like that, ideally. I like to take a 'spare' old guitar for such occurrences, but I don't always do this.)
