Vintage DiMarzio Dual Sound (Super Distortion) 4-Conductor Humbucker, Double Cream

Here is a nice clean vintage DiMarzio humbucker from probably late 70s to early 80s.  It has a 4-Conductor lead and 13.15 kΩ and the rounded mounting tabs.  It very possible it may be a special winding, or a Distortion/Dual Sound - I believe this came out of a Pedulla MVP or possibly an Ibanez Musician 15 years ago and has been sitting in a box.
