I wanted to know how my different amp sim plugins sound in direct comparison: I have Amplitube 3 and 4 from IK Multimedia, Guitar Rig 5 from Native Instruments and the VGA2 from Studio Devil.

Recently I bought the upgrade to the new version of IK Multimedia ARC. They say it has better resolution in the bass area. I wanted to find out if this is really true, so I did some measurements with REW before and after ARC2.
