Hi guys, been getting some annoying noise when playing my EMG loaded guitar through my Pod HD Bean.  My passive loaded guitar works fine. I have turned down the gain and still get noise with the EMG's...somebody had suggested that I uncheck the +18db box in the audio settings but I cant find this? 
  
I am using a Mac and are running the latest Pod HD drivers according to Line 6 Monkey...  Help? Advice?  Thanks!
