yeah.. you should be fine there. It's pretty well documented that the 12v DC power adapters/converters on laptops can cause noise with attached devices. That's one thing you've ruled out.Wow thanks for the responses guys I have a lot to try. I'm going to get behind my desk tomorrow and start trying some different arrangements. I'll also have a look at the outlet my conditioners are running off of as well. As for the usb thing that was suggested, I'm not on a laptop. Just plugged into the back of my tower. So... everything check out there?
As has been mentioned here.. the FIRST thing I would now do, is take my Axe to another location (church, school, etc.), power it up and see if the noise goes away. If it does, you'll know it's the power in your house.
