Anyone else thinking this might be a thing to try? It's cheap enough and there's good reports on sevenstring.org and some others. One dude used it with a set of Warpigs and loved it, for example. Duncan team says it's a 70/30 ratio of change, the 30 being what's retained, but other reports and threads are saying it's not that extreme at all, just more bite and clarity out of what you put into it.
