Electrical Hum

I'm not sure if this is the right area to post this, but here goes, I play Bass guitar, I have a new guitar and new bass amp, everything I play through developes a hum, In the Amp, through the Personal Aviom mini mixer, the sound tech says that it is either my guitar or my amp, when iI use the headphones on the Aviom there is a bad buzz that starts, when I play through the amp only and do not use a DI out box there is no hum, Question, can a ground look problem cause the buzz, I don't know how to find the problem or fix it, Thanks, Leaderman

What happens if you take your equipment to a different location, a whole other building?
Start a process of elimination and only change one thing at a time.
With just the amp plugged in, try a different bass using the same cord.
Try a different cord
Try your bass in a different amp.

You said the amp and bass are new so I can assume the amp has a grounded plug. What about the wiring in the building?

Years ago, before grounded receptacles and polarized plugs, just flipping the plug 180 deg sometimes reduced or eliminated hum.
