After about 10 years of playing unplugged and through smaller amps, yesterday I dusted off my 2x12 cabinet, MC250, and SMS Jerry pre-amp. I have the amp and the preamp plugged into a regular power strip, and there is humming galore when they are both turned on. (Even with no pedals.) I’m assuming this could be due to a multitude of reasons, but what are the first things I should be doing to troubleshoot? Is a power conditioner like a Furman something that might make a difference or no? I’ve never been sure about the history of the MC250 and have no idea if it’s been properly maintained so maybe that’s an issue as well. (Half thinking of unloading it and getting a Milkman… )
