As a guitarist and luthier of over fifty years, this was my personal guitar for stage and recording since new in Jackson's first year of the Soloist production. The neck and super-low action are a shredder's delight and currently strung with Darrio's thin top fat bottom strings. The pickups are all upgraded Seymore Duncan noiseless humbuckers. In 2010 I added a graphic on the front. 

From the manufacturer:

The Jackson Select Series SL1 Soloist solid-body electric guitar gives you the features you expect from a purpose-built shredding tone-machine — and more! The SL1 Soloist features Jackson's clean lines and highly functional setup, adding impressive touches such as a neck-through-body design for even more sustain, a classy compound radius ebony fingerboard, and a (gold) tremolo. In addition to its maple neck and alder body, this axe also features three great-sounding humbucking pickups (two stacked) for monster tone. 

Neck-through design

This guitar owes its great tone and sustain in great part to something you won't even notice at first glance: a neck-through-body design. The quartersawn hard rock maple neck, paired with an ebony fingerboard (adorned with mother-of-pearl shark fin inlays, no less) doesn't just join the body; it's actually part of the body! This configuration contributes to the sustain of the SL1 in a big way, since the entire guitar is integrated. You also get two great-sounding, high-output Seymour Duncan Classic Stack stacked humbuckers, with a '59 humbucker in the bridge position.
