Independent shopping perspective
The Korena take
The J-40 Standard is a right-handed, J-14 fret jumbo with a tight-waisted body shape, spruce top, and East Indian rosewood back and sides. Its forward-shifted GE-scalloped X-bracing is presented as the foundation for balanced response, projection, clarity, and sustain. The GE modified low oval neck, high-performance taper, ebony fingerboard, and 1 3/4-inch nut width support long sessions, chord changes, and fingerstyle work. It is Plek'd and supplied with a hardshell case.
