I have a few of the AMT pedals, including the S1. They're great in front of clean power amp (or straight into an effects return) and direct recording, but not so good in front of an amp as with a regular stomp box (which is not what they're designed for anyway). The basic tone from that clip is there, but a lot of what makes that clip sound so good is in the effects and cab sim, IMHO. (Not to mention the player!)
The most fun I have with those pedals is into a EH 22 Caliber power amp, believe it or not. Success going straight in to an effects return depends a lot on the amp you're using.
