Product Description

The octagonal shape approximates a perfect circle and creates a better sound.

Octacore Acoustic Guitar Strings are constructed from precision drawn octagonal core and ultra-clean phosphor bronze wrap to project optimal clarity and warmth. Hermetically sealed in foil pouches to ensure crisp sound. Available in a variety of balanced gauge sets.

Conventional strings are wound with hexagonal cores and bite the wrap at only 6 points. Octacore Strings engage the wrap with 8 gentler points to secure the string along its entire length.
