You know, that's pretty much how I've felt about that box, too! Never really could put words to it, though. It sounds amazing, but it definitely has its own sound that can't be tweaked to sound like much else. I'm always on the fence about it. I like it, but it never makes the cut on the board, or not for long.I want the lows of the blower box without the (and I may be alone with this opinion) corny distortion that you just can't work out of the sound of no matter how many different gain stages.
I should clarify though. I don't think the Blower box is corny sounding, I just didn't like that it made everything sound like the blower box when it was in the chain and on, no matter what. Killed the versatility for me. 'Twas a cool trick it did do though.
Before GAS struck me too hard, and I HAD to buy something, I dug through my extra pedals drawer. Found my old Joyo American that I never messed with too much. Might have found another fuzz to compete with my GK Rails! I'm really digging it. It'll take some effort, however, to get my sound from it. One of the biggest draws for the GK has been that I can go from low gain to high gain sounds with the Boost switch. One of my favorite songs requires me to go from low to high during parts, and that has been really great with the GK. The American does that too, but with finger dynamics. I can do that, but just gotta practice!
