If you are playing on stage your body is perspiring extensively and your body resistance is
lowered by more than 50%. This is a situation in which current can easily
flow.
Current will flow when there is a difference in ground potential between equipment on stage
and in the P.A. system. Please do check if there is any potential between the housing of the
mikes and the guitarsynth amps, which will be linked by your body on stage. Imagine, a
guitar in your hand and your lips close to the mike! A ground potential difference of above 10
volts is not unusual, in improperly wired buildings it can possibly be as high as 240 volts.
Allthough removing the ground wire sometimes cures a system hum, it will create a very
hazardeous situation for the performing musician.
Always earth all your equipment by the grounding pin in your mains plug.
Hum loops should be only cured by proper wiring and isolation input/output transformers.
Replace fuses always with the same type and rating after the equipment has been turned off
and unplugged.
If the fuse blows again you have an equipment failure, do not use it again and return it to
your dealer for repair.
And last but not least be carefull not to touch a person being shocked as you, yourself could
also be shocked.
Once removed from the shock, have someone send for medical help inmediately
Always keep the above mentioned information in mind
when using electrically powered equipment.
