The Jackson X Series Signature Adrian Smith SDXM Electric Guitar with Black Pickguard features a poplar San Dimas body and a bolt-on maple neck with graphite-reinforcement rods that refuse to budge, no matter how much environmental stress it’s exposed to. It's 12 to 16 inch compound radius maple fingerboard with 22 jumbo frets and black dot inlays is the perfect launching pad for rapid-fire riffing or complex chords.High-Output HumbuckerThe SDXM packs a Jackson high-output humbucker in the bridge position and Jackson single-coil pickups in the neck and middle positions. The humbucking pickup was painstakingly voiced for a full, rich tone while providing maximum overdrive and sustain, whereas the single-coil middle and neck pickups deliver that unmistakable Strat snap. A five-way blade selector switch with single volume and tone controls open up endless tonal possibilities, while the Floyd Rose Special double-locking tremolo system keeps the guitar in tune through any abuse you throw its way.12 to 16 Inch Compound Radius Maple FingerboardJackson pioneered the use of the innovative 12 to 16 inch compound radius design, in which the maple fingerboard gradually flattens toward the heel from its more rounded profile at the nut. This makes for comfortable and natural-feeling chording and riffing near the nut, with optimal shred articulation and bending nearer the heel.Jackson High-Output Humbucking and Jackson Single-CoilAn atypical configuration for Jackson, this guitar features a humbucker in the bridge position and single-coil pickups in the neck and mid positions. The Jackson high-output humbucking pickup was painstakingly voiced for a full, rich tone while providing maximum overdrive and sustain. The Jackson single-coil middle and neck pickups deliver that tried-and-true Strat sound.
