Clean Comp
I bought this mostly as a studio tool for my bass tracks and it works great with that.
It's very clean comp, not much color and not much noise.
It works great as a boost - turn on a little compression and jack up the output and you get a thick clean sound out of a tube amp.
I also tried running it last in the line as a limiter (before delay) to keep my input into the amp consistent. It does a great job at that if you need something like this.
