Congrats, I prefer the 70ies EB-0s and -3s to the early and late 60ies ones. Yes, the mudbucker sound makes more sense with those.
Gibson faded out the two point evertilt in 1973 when it became clear that there were delivery issues with the long anticipated separate string holder which - as Dave never fails to point our - would have made an already very good bridge concept near-perfect. Alas!, the best-laid plans, but then those missing stringholders, must have been down to the metal shortage due to the Vietnam war effort, so essentially the Vietcong is to blame for that too.
By late 73 and further onward, the stringholder delivery issues had forced Gibson to settle with the three point bridge which was, of course, nowhere near as good and a major step backward.
