Being able to switch between Parallel Humbucker, Series Humbucker and Single Coil individually combined with the blender lets you make it sound like any type of bass you want, from jazz to funk to metal. One problem that I've found is that the tone knob doesn't seem to make much difference, and I've seen the same problem in a 4 string SIRE V7 from a friend of mine. On the other hand the active equalisation is really sensible.
