What players and reviewers say

On the Bare Knuckle Holydiver

The Holydiver pushes a broader low-mid voice with a smoother top-end contour and a more elastic feel under gain.

The low mids punch hard with that unmistakable 80s hard rock chest-thump that makes power chords feel enormous.

The high end sings with an edgy sweetness that has bite without being shrill.

The upper mids and the high end are more about clarity, so notes are more precise and less nasal on the high end.
