I usually don't do this sort of thing (write reviews) but I felt like I needed to help spread the word about this plugin. First off, this is nothing like dealing with eq or sample replacement. It's a totally different bird, because of that, it's slightly hard to wrap your head around what's going on under the hood. After a few hours messing with it this morning and watching the tutorial videos I'm hooked, For one you can make bass drops really really fast. It's also super good for beefing up kicks and adding attack. I generally use at least 3 kick samples but with this plug it isn't necessary. My only complaint is that it could be more intuitive. Overall this is a damn good first offering.
I agree entirely with TheDude86. It's a totally different way of working that EQ or sample replacement. Those are familiar now, but certainly didn't start out that way. In my beta tests of Sasquatch it took some time to get my head around what it was doing, what it was great at, and what it was not-so-great at.
For me, Sasquatch has been a breath of fresh air. I use it just about every mix now. I'm fully addicted to Sasquatch and I wouldn't want to work without it regardless of whether I'm doing hip hop, metal, or dance.
