Brad Jetter knocked this one out of the park. I've never played through a Trainwreck amp, and probably never will. I will say that this pedal, regardless of what it's supposed to sound like, is the best OD pedal I've ever played. It has excellent string separation/clarity even at higher gain settings, and responds terrifically to volume/tone knob adjustments on your guitar. I couldn't be more pleased. Greg Koch has a great demo of one on youtube for Wildwood Guitars, I'd recommend checking that out and it will give you a good idea what the pedal is about.
