Yes that's personal preference of course. The more you have the high cut to the right the more ring modish/distorted (or whatever you want to call it) it sounds. To the left makes your octave much cleaner and more like a traditional octaver pedal like the Boss OC-2. The Boss has that synthy octave sound that the ring mod also has unlike the octave divider in the Pitch block.
What I was trying to say is that before I never touched the high cut to get that octave sound and now I have to use it to get the same sound as before. Don't want to be suborn but that is what my ears say. Before I had the feeling that the high cut had less effect on the overall ring mod sound and now it does have more effect which is a good thing. But maybe I have lost my mind
