Why this grade

Where these two actually differ

  • We flag Nickel skin contact sensitivity and Coating degradation and core exposure on the D'Addario and not on the Ernie Ball.
  • We flag Steel core oxidation and rust and Undisclosed chemical additives on the Ernie Ball and not on the D'Addario.
  • The D'Addario is Nickel-plated steel core with nickel-brass wound exterior where the Ernie Ball is 80/20 bronze wound strings with proprietary light coating, which is most of the difference in these two grades.
  • The gap is 35 points, wide enough that this is not a close call, and the D'Addario is the one to buy.

Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
