What's the difference between a Super Distortion^® and a Dual Sound^®?

In our current production, there is no difference whatsoever, but we include a 500K push-pull pot with the Dual Sound^®. Our original Super Distortion^® had 1 conductor plus shield. We introduced the Dual Sound^® with three conductors plus shield to allow more wiring options. As guitar manufacturers and players became more sophisticated, the market demanded four conductors plus shield on all humbuckers, so both models now have four conductors, as do all of our full-size humbuckers.
