I really like it and find it plays really well with other pedals. It sounds amazing with the RC on before it. The Comp and Amp Sim work great together and, in fact, never use them on their own. The big thing to note is that the Comp is a limiter where Sensitivity is adjusted based on input and Comp is how much limiting you want. The Output directly feeds the Amp Sim. So cranking the Limiter Output will cause the Amp Sim to distort, and it's pleasing if that's what you want, but I prefer to lower the Output and increase the Amp Sim Output so that it can relatively clean with small amounts of Gain added.
The fuzz is useful and has many tones depending where on the input dial you've got it set. I use it sparingly at most. I want to experiment putting the Station earlier in the chain so I can add some modulation after it. Then I think I'd use the fuzz more. Maybe. Hope this helps!
