One more thing I borrowed was a Roland VG-88 which does essentially the same thing as the Variax (modelling, modelled instruments and tunings, etc) but is instead a floor unit - again, very convincing Rickenbacker 12 String sounds coming out of that and all it needed was a standard guitar with a special pickup mounted on it (again, a piezo).
That's ironic piece of gearhead gear, isn't it? It's a gadget that functions against gearhead mentality: Buy more gear!!
