Description Ernie Ball welcomes four new half gauge combinations to its world-famous Earthwood line of acoustic guitar strings. Ernie Ball’s new Earthwood guitar sets feature the same great bright and balanced tone that Earthwood strings are known for, in new never-before-offered gauge combinations. Custom Medium and Custom Light offer players more options to select their optimal balance of tension, projection, and playability. Both sets are offered in phosphor bronze and 80/20 bronze alloys and feature tin plated high carbon steel plain strings.
