What players and reviewers say

On the Bare Knuckle Ragnarok

“The Ragnarok neck has the same syrupy but clear mids and top end of its bridge counterpart, but with a more reduced low end.”
bloughlin16 · 2023-03-06Seymour Duncan forum ↗ (opens in a new tab)
“The combination of a substantial low end, strong mids and controlled highs gives the pickup enough personality to remain interesting as the gain comes down.”

On the Seymour Duncan Invader (SH-8)

“Invader was muddy, and the JB's mids were annoying in the SG.”
Fusion1 · 2004-10-05Seymour Duncan forum ↗ (opens in a new tab)
“I wouldn't want a super thin pickup in the neck with a super thick one in the bridge, which is why I wouldn't through a Jazz in alder with an Invader bridge.”
