If you really want a wierd sound, use an Electro Harmonix Bass Balls pedal. Its a twin Dynamic Filter, so its like you can control the filter sweep with the left hand. It sounds great, and it will boose the sound so much that you can hear strange ghost tones from the volume antenna at high high volumes, just immediately outside the oscilator range from the pitch antenna.
