| Stuff like that happens and sometimes it can be pretty hard to track down. I did a gig last Christmas going directly into a pretty crappy PA and the bass signal kept dropping out. It seemed like a dodgy lead but I had similar problems with other leads as well. I think I may have changed the battery after the gig, just in case, but it might just have been the PA channel I was plugged into.
I also remember attending a Steve Lawson / Michael Manring clinic at the Bass Centre in London and Michael's rig choked and died halfway through the first song. A quick change to Steve's rig and he was back in business - I can't remember what the cause was but I think it might have been something not securely plugged in round the back.
Mind you, if I'd been cutting together the DVD, I think I would have tried to drop in a scene of Victor putting down one bass or picking up the other, assuming there was a suitable drum solo where the switch could have happened.
