This is the 70's in a box. It doesn't get any better than this tone-wise. There are some major downsides to it tho. As opposed to the little pi, this one is built with flimsy metal that can be dented if you stomp it too hard. It isn't compatable with any normal 9V power adaptor, just an odd one that has a 1/8 inch input and looks like a headphone jack (don't be fooled, it IS for power). It's also really big, and not too easy to fit on a pedal board. It also doesn't sound too much different from the little pi, but there is a discernable difference. If you are willing to overlook these downsides tho, it's one of the best sounding fuzz's that you will ever play on.
