I'll try to be more precise. I am referring the amount of backlash between clicks as "slop". They both perform in a similar manner, but the Fractal knobs feel like a Lexus, while the EC knobs feel like a Toyota.
As for configuration, you can set a min, max, and step value. So if you use the defaults of 0/127/1, it takes over 6 complete rotations to go from min to max. I expect its viability as an expression pedal replacement comes down to the actual target device & parameter(s).
I'm liking this thing more and more the deeper I go.
