I’m with the stock sag pot, and it works full range. I run at 18v though; but the sag does it’s thing, albeit with a finer grain, very nicely. Just last night had it around 3 o’clock. As I was playing, I got to thinking about how much that knob does, and by such “simple” means—compression, narrowing the freq. response, extra texture, etc., all from a bit of voltage control. Really wondeful.
