Detailed Explanation:

Hello

I have a POD UX2 that I just purchased on Tuesday and I'm doing in home recording with it. When recording with my bass (which has active pickups), I get a lot of feedback ringing when close to my computer. I turned off my wireless, and still I get the ringing feedback. I don't believe it has anything to do with my POD. Also I just noticed when recording with my electric guitar, audio from the backing track I'm recording with is dimly playing through the recording track during playback....What i mean is after I record a  new track with an electric guitar, I play back the recorded track (in cubase) while having the backing track MUTED. When listening to the freshly recorded track only, I can hear the backing track playing through faintly. I further tested this by recording with the backing track again however without playing guitar and when I play back the recording, I can hear the backing track playing quietly again through the recorded track. It reminds me if I was blaring my headphones while trying to record vocals. I am using Vic Firth sound cancelling headphones on a low setting to monitor. I monitor through the POD. I have tried putting the output in cubase as NO BUS and it has no effect. I have recorded with my friend's UX1 (on a different computer) and had none of these issues, nor has he ever encountered such issues. Is it a POD issue? Perhaps the POD is picking up its output and treating it as input along with the guitar? I am stumped.

Thanks in advance for any help!
