I've played a Duesenberg once, but I can't remember how it sounded or felt! With VR, Duff plays mostly Fenders, a black Aerdodyne one, his signature one in white and I think another signature one in black. They all sound similar, deep lows and snarling highs, hardly any mides so as to not get into the way of the guitars, he picks right over the splitcoil and must have the pups close to the strings, so its clacke-dee-clacke-dee-oooomph-oooomph all of the time. He probably switches basses because they have different tunings (they're all four strings). When he played the Duesnberg, he suddenly had rich mids and a more subtle, less focused low end plus the snarling highs were gone. He used it for the more ballady stuff only.
