Its a long shot, but I was hoping that Gene or others with good
electrical experience might help.


Well, some friends of mine have a pretty good local band, and they
play at various venues around a tri-county area. OK, so I went up
town
to hear them Sat. and one member and I got to talking on their break
and he asked me so i thought I'd try to get some ideas here.

One place they play is an older brick building with everything that
can plague an older brick building.


I'm sure the wiring is sub-standard and I dont' know if it has
fluorescent lights causing fits or not. But all the amps and PA have
a
"hummmmmm" that they can't get rid of. The guitarists amp hums the
worst. Not totally obnoxious, but really annoying.


It seems that today's equipment(for the most part) doesn't have any
provisions for a "reverse" switch on the amps, and with three-prong
plugs it's kind of hard to do the old "turn-the-plug-around" trick.


Even with a reverse switch, I've seen instances where when flipped the
hum only got louder.


The manager says all the bar/ kitchen equipment is in good order, ,
but that's left to be seen.


So my question is, does anyone here know of any type of device/ power
bar etc, that can help compensate for this type of a problem?
All these players have good late model quality equipment and this is
the only venue they have this problem.


it's a good gig for them but event the patrons come and ask them
"what's the hum?" They don't know, I don't know.


Any ideas?


Thanks!
