Hello everyone.  Just picked up a POD 2.0.  Prior to, I've been using GR3 and Amplitube 2 but never got the sound I was looking for, they came close but still not quite there (a bit too harsh for my liking).  I tried the 2.0 for the first time and the results I'm getting are better but still just OK.  My chain is quite simple - guitar, POD 2.0, Native Instruments Session I/O usb interface (which came with GR3 Session), DAW.  I'm wondering if the hitting the usb interface after the POD is not enough and I should be using a mixer between the two.  Anyone have any advice on this please?  Thanks.
