After many years off letting anyone play through my gear, I think I've finally hit that point where I might not any more.
As others have said, if my stuff gets bust, I can't afford to replace it, and why should I? If I can take care of it, surely they can? I've seen too many people just pull leads in or out without muting or standby etc.
Had a cab blow once, but didn't find out till I got it home
I feel like a @rse being that guy who says no though
