Configuration very simple.Même whether to spend a little time (like everything).
The "Blend" is really the richness of this mixture pédale.Le clean / compressed sound is definitely a plus.
Impossible to have a boss cs3 compression type plastic (which I learned to love, just for this side plastoc and exaggerated). The ego comp does wonders on tube amps (supersonic and princeton for me) and is slightly less reactive (magnifying I would say) in front of a preamp (SS 20 for me). I do not hate anything in this pedal, it brings something thick and clear sound (sometimes to the point that we want to leave switched on all the time). Used with an electric guitar and sometimes a jazz bass.
Used for a year.
Pedal very expensive but that is the job.
