I was playing my guitar about ten minutes ago and all of a sudden the signal cut and I
couldn't work out what it was.
I unplugged everything and tried to work out
what was wrong but nothing came from it. I even tried all of my guitar pedals separately
and they all worked fine. Connected them back together and I had sound again.
After a few more minutes of playing I could smell something burning. It was that
electrical burning smell.
Turns out that the spare power link for my effects
pedal was touching the side of my boss NS-2 and was creating a whole load of sparks that
almost set my G-bone (gator pedalboard) on fire.....
I have stopped playing now
and I have everything switched off and unplugged.
Anyone got any idea what the
hell was causing that to happen?
The shell of your metal pedal is at earth potential.
The outside of a 9v
adapter plug is at 9v.
Touch the two together and you have a circuit. As there
is very little (if any) electrical resistance here then current flows to the greatest
extent the regulator can supply. That explains the sparks and the burning. As others
have said, tape is your friend here though (depending on your PSU) you might have other
issues now in terms of something having got a bit melty....
