It was actually good. I started using it the way the guy in the article described, and I like it a lot better. I can hone in on the sweet spot much much faster now.
Basically, he sets his compression level, sets the R37 control all the way counter clockwise, and slowly turns it clockwise until he hits the sweet spot. I always did it in reverse. I have to admit, I really liked the results I got. But I'm only using the Pro Channel version.
