As a simple compressor, this thing works beautifully. I've had luck using it on a variety of sounds, and it really is a no brainer. Anything from pads, to leads, I've had excellent luck with. Even basses are beautifully handled. The saturation knob effects how much goes itno the mix, and the One Knob changes how much is truly compressed or tightened. I would highly recommend for anyone who loves the KISS principle.
This, and its cousin plugins, are must haves for a simple fix or effect. Not bad for the price of free, either.
