Bought me $300 worth of pedals the other day and I couldn't use them. Showed up to play, plugged in my L.R. Baggs DI box to the mic and let it use the phantom power, then I plugged a Boss AC adapter into my tuner pedal, and used a daisy chain from the tuner into the Aura. I'm getting a hum, and had to bypass the aura and tuner. It's very clean with just the DI box. Is there an easy remedy? I've heard that it could be as simple as taking the AC adapter and turning it upside down.
I suggest an Ebtech Hum-x they are about $60 american. It worked for me.
