Mike,

That sounds like a good test. Might be a little difficult to set up with an Axe, but certainly worth trying. Thanks for the heads-up.

MMatheny,
I seem to recall reading that it is Counter-Clockwise to increase sensitivity. Be sure to mark the original setting with a Sharpie pen, so you can 'follow the bread crumbs home". And, Remember to power down and back up (unplug the bat for 10 seconds or so, then replug) after making adjustments (something about letting the circuits re-initialize after adjustments).
