Don't forget that single coil guitar pickups (traditionally Fender types) pick up a LOT more noise than humbucker pickups (traditionally Gibson types.) You probably already knew that. Single coil pickups are very sensitive to hum, in my experience. They sound great though.

Hello folks,

I just picked up a nice guitar amp, one of
the better made ones (Mesa Boogie) and
running it at night I found I was getting
buzz that mostly all goes away when I
touch the strings. Trying to track it
down, there was no hum with the 1/4:"
instrument plug removed from the amp. I
soon found much of the noise to be coming
from the lights on a dimmer switch.

With the lights out there's still some hum
that goes away when I touch the strings,
but that's for me to the track down next.
For right now, I would appreciate knowing
what wall switch dimmers I might get that
are known to be acceptable?

This particular one is many years old, one
of the ones you push in to turn on/off and
rotate the same knob to change the
lighting intensity. It fits in a single
switch wall socket. Though it's not
getting into my radio that I can tell, it
does need to go.

Any suggestions of a known well made &
friendly dimmer?

Thanks & 73,

Gary
