What players and reviewers say

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.

On the Seymour Duncan Original Parallel Axis (PATB-1)

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.
