What players and reviewers say

On the Bare Knuckle Rebel Yell

It’s dynamic response at stage volume with the ability to go from glassy clean to full saturation without collapsing into mush.

Where a lot of pickups in this range get compressed and narrow, this one stays open and articulate.

On the Seymour Duncan JB Model (SH-4)

The Full Shred is a tad lower in output and gets close to the lead sound of a JB.

JB is very touchy. It likes the heights about the same on the high and low side.
