Why this grade

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 GHS.
  • We flag Coating composition opacity on the GHS and not on the D'Addario.
  • The D'Addario is 80/20 Bronze (copper-tin alloy) with phosphor-bronze coating where the GHS is Hexagonal wire core with unspecified 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.
  • We are less certain about the GHS grade, at 35% confidence against 82%, because it discloses less.

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 →
