Irig 2 macbook pro w/ garageband or AmpliTube.
I just purchased it, and everytime I plug it in I get only feedback. It seems to be using the on-board mic and not the Irig 2. I've looked all over for a way to turn the mic off but cannot seem to do so. Any tips? I'd hate to unistall then reinstall and really want to start using this thing!
