We just moved into a 60 year old house and discovered that my daughter's
electric guitar and amplifier won't work properly. There'a a loud hum
coming from the amplifier. It stops when she puts her hands over the
strings, but starts up as soon as she removes her hands. Could this be a
grounding problem? Any suggestions? (There's nothing wrong with the guitar
or the amplifier. She also has a bass guitar and a bass amplifier and the
same problem is occuring with them too). Thanks.

Amazing!

Do you have a long 3 prong extension cord? Try using it to plug
into a known properly grounded receptacle and using it instead and see
if it helps.

Do you have a three pronged plug on your amp?

Were you talking about a grounding problem between the guitar and the
amp, or between the amp and the wall? I think it could be either, but
I'm assuming the guitar is like a turntable. (It probably is.)

If you meant the amp and the wall, you seem to know a bit about this.
I'm surprised you would plug a 3-pronged amp into a 2 pronged outlet,
so maybe the outlet has 3 openings, but the ground is no good there.
To find out, get a volt-ohm meter, or get one of those cubes with
three prongs and 3 leds and see if you have a good ground.

Let us know.

If it doesn't then you have other problems.
