Overview
A player moving up from light strings gets a bit more body from this Ernie Ball set, which wraps phosphor bronze wire around a brass-plated hex-shaped steel core. The gauges run from thin trebles to a heavier low string.
The reason to buy is a rich tone with clear trebles from a defined bronze alloy, in a medium light gauge that balances volume and playability. The limitation is that the coating is listed as both coated and uncoated.
Who it's for
Strummers and fingerpickers with a steel-string acoustic who want a warm bronze sound. A player after a very light feel, or a guaranteed coating, should confirm the details.
Pros and cons
- Defined phosphor bronze alloy
- Hex-shaped steel core
- Medium light gauge
- Rich tone with clear trebles
- Coating status contradicts itself
- No warranty listed
- Gauge notation differs between fields
Performance notes
The hex core grips the wrap wire so the winding stays put, and the phosphor bronze alloy gives a rich, clear voice. A medium light gauge takes more finger pressure than a light set but produces more volume. The listing offers no coating or longevity claims beyond its conflicting fields.
