A real "duuuh" moment from me, not computer related, though
I set up my rig in preparation for a gig. Switched on, left the thing on standby, grabbed a pint, came back to the soundcheck. Soon as I hit the On switch, the thing gave out the most horrible hum ever.
Opinions ranged from dud cables, ground loops, faulty switches, faulty power supply on me effects board, to busted pedals. Tried all kinds of things except the obvious.
I felt a proper idiot when I worked out the cause. I have some of my pedals in front of the amp and some in an effects loop, which for those who don't know, is an output from the preamp (Send) to which you can then connect various effects and plug the output of those into the power amp (Return) I'd left the effects loop cables draped over the amp, right across where one of the transformers lived. Moved them away to where they live on the floor and silence (or as near as you get with a big valve amp) reigned.
Yes, I got a lot of stick for it. No, I've never done it again.
Biting the hand that feeds IT
