The SL1's combination of thru-body neck, heelless construction, fast neck profile, and compound-radius fretboard give it a feel and sound like no other. Seymour Duncan pickups and Original Floyd Rose tremolo come standard. Features alder body wings, maple neck, and a bound ebony compound-radius fretboard.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. With a more relaxed hand, you'll play better!
