I had one of these years ago. I kinda wish I would have kept it and wouldn't mind having another (if, for nothing else, nostalgia), but it was noisy and inconvenient. It's basically just an op-amp big muff with a Soul Preacher compressor in a big ass box that only runs on AC power.
If you want an op-amp muff without the compressor, you might want to check out Stomp Under Foot. Matt's stuff is great. I have one of his Violet Ram's Head clones. I'd like to pick up his Civil War Muff:
