I agree with many of the comments above. I’ll add that I initially made the mistake of max’ing everything out. Distortion, right? Crank it. But there are loads of subtle combinations in the Sculpt algorithm. All of my first preset attempts (and most of the [F]actory presets) keep the MIX pegged at 100.
Setting the MIX low (even down to 20) gives you some nice ‘parallel compression’ options. Attack, *and* spectrum shaping. Presets that sweep filters can sound like a doubled line, or descending ambient wash.
