The Nailbomb uses alnicoV magnet, and the Cold Sweat is a ceramic magnet. Directly compared to an EMG, I think that the Miracle Man would be the closest in terms of output, the the Nailbomb will give you serious crunch as well. The Cold Sweat, theoretically, should have better "cut" than the Nailbomb, but I've not yet put my CS in yet (within the next 2 weeks, I hope -- rumour has it that my neck will ship very soon).
