Alder body, maple bolt-on neck with rosewood compound-radius fingerboard, 24 frets, sharkfin inlays, and a 25-1/2" scale. 2 Duncan Designed Detonator humbucking pickups, and a JT580LP double-locking tremolo.Jackson's compound-radius fingerboard curves more dramatically at the nut for easy chording, and flattens out as it approaches the neck joint for low-action bends without fretting out.
