I saw that Bruford band with Berlin on tour, and they did Joe Fraiser, which was killer. They also did the song that was the prototype for King Crimson's "Indiscipline" a few years later, the asymmetric pulse over which Bruford did his amazing fills. I'm pretty damned certain Berlin was playing through an SVT, but most of that sound is from his fingers - a very, very powerful, fast and precise right hand.
