FWIW I've only ever seen one previous reference to it here, and I think it was from somebody else asking the same question. So I'm betting the answer is "You buy it and tell us!"
I have the pedal and the onboard version in one of my guitars (Tyler HD). I have tried it with a few basses before but it was a bit too muddy sounding for my tastes. Great on most guitars I've used providing them with a bit more thickness.
