Independent shopping perspective
The Korena take
Built around a seven-string layout, the JP157 DiMarzio pairs a LiquiFire neck humbucker with a Crunch Lab bridge humbucker for defined lead and rhythm voices. The three-way selector, master tone, and push/push volume boost keep those options close at hand. Its roasted maple neck, ebony fingerboard, 24 frets, and 16-inch radius give technical passages a focused playing platform, while the tremolo and locking tuners support expressive pitch work. A nyatoh body and flamed maple veneer top complete the Purple Nebula finish.
Strong match
Who this is for
- Extended-range riff and chord work that benefits from a dedicated seven-string instrument.
- Moving between detailed lead lines and focused bridge-humbucker rhythm sounds during a set.
- Players wanting tremolo expression alongside locking tuners and a push/push volume boost.
