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 GHS.
- We flag Coating composition opacity on the GHS and not on the D'Addario.
- The D'Addario is Nickel-plated steel core with nickel-brass wound exterior 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: 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 →
