On the subject of dimmers.....many years ago, our band rehearsed in the basement of a home. For a very long time, we would have random/intermittent hum and buzz problems with the guitar amps that we could not figure out. It would come and go with no pattern. Would be fine for days or weeks and then unbearable for one day...two days.....who knows. After literally years of wrestling with this, I discovered there was a dimmer in an upstairs room that, if it were set anywhere other than full off or full on, would make the gear in the basement buzz!! Since that discovery 30 years ago, I have told countless people with buzz problems about this and, in many instances, they found a dimmer causing the same problem at their place. Of course, for a number of potential reasons, the guitars are most succeptible to it. Can happen at home, a friends house or even at a gig where there may be a dimmer in the building. It is nearly impossible to filter it out with any of the "line filter" gadgets. The only way to stop it is to find the dimmer and turn it off or on. I have even had customers bring amps in for buzz/noise problems only to discover it was being caused by a dimmer in their home.
