Rat King sounded more like a Rat to me, but it was way too big. Blower Box sounds rad, but not really like a Rat. My solution, by a Pro Co and mod it for bass. Beats them both, for me. I can see both sides, though. It's hard to argue the Blower Box is as versatile as the Rat King. Conversely, it's hard to argue the Fuzzrorcious is as well suited to bass as the Blower Box. I think the real problem here is they are apples and oranges. 'Rat based" does not actually mean "Rat clone". Two different tools, IMO. Since this is a BB thread though, I will end with this: For the money, its a steal, and it does sound awesome, even if not patently rattish. And now, with the smaller enclosure and the volume knob moved from the top, I will get one, but not for Rat needs, as that's covered by an actual Rat for me. But its still a killer pedal to have around.
