Overview
A busy performer gets strings that start with the highest tensile-strength core, tin-plated on all six for added corrosion resistance. The wrap is bronze, and the set is named for custom light gauge.
Corrosion resistance and tuning stability are what the maker focuses on, in a gauge that is easier on the fingers. The limitation is that the listing does not state tension and the finish is simply bronze plated.
Who it's for
Fingerstyle and flat-pick players, bluegrass strummers and anyone who practices a lot. Heavy strummers who want a thicker string should choose a heavier gauge.
Pros and cons
- Tin-plated core on all six strings
- High tensile-strength core wire
- 80/20 bronze wrap
- Custom light gauge
- No tension figure
- Warranty listed as not applicable
Performance notes
A tin plating on the core slows corrosion where the eye cannot see. The bronze wrap gives a bright, balanced sound, and the high tensile core supports stable tuning. A light feel helps with fingerpicking and long practice sessions.
