Michael, these 4 paragraphs explain the essentials nearly perfectly, well done!

Having played both in my stage rig, I think the D-Bob and the standard Q are very nearly indistinguishable in sound. The D is more compact and slightly easier to tweak and you pay a little more. Either one could sub for my vintage Mu-Tron in a heartbeat.

Since it's triggering is dependent on the input signal you have to alter your picking so that you aren't peaking it too soon or not enough. You can dial in the sensitivity to roughly match your picking style - it just takes some getting used to.
It's also very sensitive to effects that are upstream of it as well as changes in volume from the guitar.
+1,000,000!

I would add that anything upstream that isn't true bypass will flatten out the effect in a bad way, even when bypassed (OFF).
