I bought a Cole Clark Fat Lady a few years ago (when they were first imported into the UK, most expensive guitar I own and my favourite acoustic. Did a gig up in the Lake District and thought it would be a good chance to test out my new guitar and my new mic (Shure Beta 87 - my most expensive mic). Everything set up and taking a breather before going on and some twonk knocks the mic stand.
Cue my slow-motion horror as the brand-new mic plunged towards the top of the brand-new guitar...
But these things happen and after a while you stop noticing.
