Can moving wire location at circuit breaker reduce hum?

The power line going into my music room will oftentimes make the amps’ transformers hum.  I’ve tried many things but have had no luck.  If I take any component that’s humming into a different room run on a different circuit breaker, the hum disappears.

Would swapping out the wires that go into the two separate rooms at the breaker make any difference?  Or is it more likely that one of the outlets on the circuit that goes into my music room is somehow miswired and is causing the hum?  I can unplug everything from the circuit except for my amp and it still hums.

Any suggestions on what I might be able to do short of hiring someone to run a dedicated line?

Thanks,

Mamoru

Here's a great meter to use for basic testing, including Neutral voltages:

Fortunately, the first test, to identify if this is caused by another electrical component is fairly simple.   Turn everything else off in the house. 😀

Flip off every breaker and make sure nothing is left on your circuit but your amps.  If the problem is gone, you know it's something else, and that's my bet, but yeah, it could be a bad neutral.

Give it a shot, you have nothing to lose!

     A lot of pro (instrument) amps have phase-reverse switches, to deal with hum issues, on stage.

     Those suggestions on the outlet wiring tester, to me, would be a good/basic place to start.

     Hots of all outlets in the room, on the same leg, in the panel/breaker box?

                                                    My 2 cents.
