If you don't want to mess with changing the AC cord on
a vintage amp with a two prong plug, make it safe with
a wire attached under one of the metal straps on top
of a Fender amp, and an AC plug at the other end with
the wire connected to the GROUND pin ONLY!. Plug this
in along with the 2-prong POWER cord, and you will be
grounded.
If you use equipment with only a 2-prong AC cord,
figure out {before you get to the gig} which way to
plug it in
with the POLARITY SWITCH in a position you will not
change, that has the least amount of hum/shock
potential, then MARK the plug so you know which way to
plug it in for the future. I use a Sharpie pen to mark
the side that will be closest to the ground hole on
the wall outlet. All this is dependent upon the wiring
of the wall outlet to be the same as where you first
made the test. Get a yellow polarity/wiring tester
from Radio Shack so you can see if the
bar/dive/girlfriend's house is wired to code.
Remember, only one ground pin in a system
-Reverb-Echoplex-Amp. The amp is the obvious choice
for using a ground pin. Redundant {more than one}
ground pins causes hum.
What happened to DD when he touched that mic was the
polarizing capacitor in that Showman emptied itself
into his lip, and, or, hand. Heads should roll! Before
you apply a body part to a mic/guitar combination,
while not touching any metal parts of the guitar,
touch the guitar strings to the mic, and watch for
sparks. No sparks, no shock potential.
