I've tried using Guitar Rig with different inputs for a long time (PC in, M-Audio Jamlab and then interface on the Zoom G5) and am always really happy with the clean sounds, but every distortion I try always come out flat and fuzzy. Absolutely no punch at all.
Even the sample configurations (which should sound nice) they provide sound awful, no matter what I try (different amp simulations, mic placement, effect pedals, EQ).
I understand it's absolutely not a replacement for the real deal but I've heard recordings done with Guitar Rig (or other DSPs) that sounded very nice and I've never been able to reproduce that. If a multi-effects pedal can accomplish good distortion sounds, it should follow that a PC can do better.
So what am I missing? Is there a way to get good distortion from a software like Guitar Rig?
