Here are a couple of clips of the AC4 if that helps. They were simply a bad room --> Epi Les Paul with 57 Classic pick ups --> AC4 --> SM57 --> Firestudio Project --> Cubase --> Geaslutz =]
I put a Boss DS-1 in front of the distorted tone since it was kind of late and I didn't want to crank the amp to get it's sweet overdrive.
You can hear the clips here:
