Doing a bit of digging, found these in the link below;
7 string models = 57-7H, 60-7H, 60-7HX, 66-7H, 81-7H, 81-7HX, 85-7H, 85-7HX
8 String models = 57-8H, 60-8H, 60-8HX, 66-8H, 81-8H, 81-8HX, 85-8H, 85-8HX
*Models with screw pole pieces are shipped with
matching pole pieces. To change the color of the pole pieces additional screw pole pieces
will need to be purchased separately)
Q: Will EMG be making plastic versions of the stainless steel 7 & 8 string H caps?
A: Yes, we are planning to introduce plastic versions of the 7H & 8H caps at some
point…not sure where that will land on our list of priorities just yet. Molds are costly,
take time and patience, every new plastic mold we create takes 8-9 weeks of labor once
the all the mechanical plans and drawings are in place and approved.
Q: Will EMG be offering the 57/66 models for 7 & 8 string in the 35 & 40 soapbar
A: Yes, this is on our list. Be patient. Stay tuned.
I really dig the 57/66 set I have in my Xtone, I wanna try them in my RGA8
