What players and reviewers say
On the DiMarzio Sugar Chakra
“There is some bite in the high end, but more of a refined treble that gives weight to the notes.”
“The trick is to manage the high end on that slope's sweet spot.”
On the Seymour Duncan JB Jr. (SJBJ-1)
“The JB Jr sounds like it has great crunch on the bass, good mids but way too ice-picky treble.”
“The JB Jr sounded bright, almost glassy and the mids seemed, well nasal, if that makes any sense!”
