This is a Fernandes STJ neck, Jackson type. I received it from an acquaintance and it has been unused for a long time, so the details are unknown, but since it has a Jackson headstock, I believe it's from the late 80s to early 90s. However, it's unusual for a Fernandes to not have a string retainer bar, and there are no mounting holes, so it might be a TEJ neck modified for a locking nut, but the details are unknown. Long scale 22F, fret life approximately 60% Rosewood fingerboard, locking nut specification Neck end width approximately 55.5mm Condition: I haven't strung it up and set it up, so I can't confirm with high accuracy, but when I place a ruler on it with the truss rod loosened, it's almost straight. *This is a visual inspection. Also, there are noticeable fret irregularities, especially on the lower frets, and frets 15 and 16 have scratches, so please consider that fret leveling may be necessary. *Due to this condition, it is recommended for those with some experience in adjustments. Thank you for your consideration.
