Man, I've been listening to your clip over and over agan and that is definately one of the best tones I've ever heard! Those riffs are so sick too. I've been debating whether or not to get a Mark IV or some sort of rectifier (most likely a Roadster), and I am really leaning towards the Roadster. From variuos clips that I've heard of both amps, it just seems that the rectifier is much thicker and warmer, while the Mark series seems kinda cold and sterile to my ears. I don'y really play super fast riffs all that much anway, so I don't really think the Mark IV would be for me. How well does the rectifier handle faster stuff? I've heard Buckethead doing plenty of fast stuff with his LP and triple rectifier and it sounds pretty awesome to me. What's your opinion on that? Anyway, again that's such an awesome tone.
