On the Seymour Duncan Hot Rails (SHR-1)

Sure, it has some low end punch and a dominant midrange.

On the Seymour Duncan JB Jr. (SJBJ-1)

It is actually voiced much better for punch and clarity in a neck position that one might expect.
Darth Phineas · Oct 13, 2021Darth Phineas (opens in a new tab)
Sort of that sweet spot if you think the Hot Rail neck has too much brawn and the Little 59 neck has too much spank.
