Where these two actually differ

  • We flag Coating degradation and particulate release and Allergic contact dermatitis (copper sensitivity) on the D'Addario and not on the Ernie Ball.
  • We flag Nickel contact dermatitis and Hexagonal core fracture and sharp edges on the Ernie Ball and not on the D'Addario.
  • The D'Addario is 80/20 Bronze (copper-tin alloy) with phosphor-bronze coating where the Ernie Ball is Nickel-plated steel wound around hexagonal steel core, which is most of the difference in these two grades.
  • These two are level, close enough that price and fit should decide it rather than our grade.

Both products run through the same public rubric, which covers 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 →
