hey man, I don't have any clip of my TA, but I can say you will get at leat 80% of Metallica tone from the factory PRESETS, and another 10% from your tweaking, so there will be at least 90% of metallica tone at your finger tip, just buy it and enjoy.
hehe it's very close
BTW here is Dark Alone's TA clip, hope you like it, http://www.darkalone.com/triaxis/drew-*****.mp3
I think it's very close to Metallica's tone.
