Do most of us have 5 different overdrives in the pedal board? It takes guitarists to do weird stuff like that.

All the bass players I can recall that I know personally all have a certain sound in their head that they are persuing. If that cab gets them that sound, they care that it can do it, not how it gets it done. Of course, that's a really wide brush to paint with, but I don't know of any that change speakers unless they're blown or damaged. Most of us will replace the whole cabinet rather than the drivers.
