I had a Randall tube HT-100? several years ago, which I think is what Dime used for a lot of Pantera albums. It wasn't a bad sounding amp, but it really didn't define 'the Dimebag sound'. He most likely beefed up the front end of those Randalls with rackmounted OD's, and suppressed the heck out of it with noisegates, to tame the hiss. IMO, that's the Dime sound, although those Kranks will get you there as a plug in and play amp. Right after the Kranks came out, I had the opportunity to play on a Revolution 100 halfstack at blazing volume at my friend's store. It wasn't entirely my thing, but there's no denying that the Krank is a worthy metal amp. Too bad Dime didn't get the opportunity to make more CDs using the Deans and Kranks. Too bad.
