built late 1990s and early 2000s—the SL4 comes with 22 comfortable frets-humbucker pickups and Takeuchi JT 580 lp bridge units, as the model was coming in solid-trans-quilted maple finishes. Alongside the American lines of Jackson guitars there was other economic line—in prices—from 1987 until nowadays that called Pro lines for all Jackson models, and the top of these models in Soloist model were the 1990s models until 1996. SLSMG The SLSMG (Super Lightweight Soloist MG) is the entry level Soloist model and belongs to Jackon's MG series guitars. It features the neck-thru design that is obligatory for any Soloist. Along with the discontinued U.S. made SLS, the SLSMG is one of the few Soloist models not to feature the traditional pointed Jackson headstock with six inline tuners. Instead the headstock is fitted with a three tuners per side setup. Models released prior to July 2006 featured passive EMG HZ-H3 pickups while models released after this date are equipped with active EMG 81s and 85s in the bridge in the neck positions. The SLSMG's carved body is made from mahogany. The string-thru design makes the SLSMG one of the few Soloists without a Floyd Rose tremolo. All SLSMGs are made in Japan. Chicago MG Jackson briefly partnered with Washburn International with headquarters in Vernon Hills, Illinois and for a short time manufactured a version of the MG model on Elston Avenue in downtown Chicago. Additional models of the MG were imported for Washburn to Jackson's specifications. At that time, Jackson began to experiment with CNC equipment to customize the geometry of individual necks to the requirements of various artists. Other MG components were precision CNC machined by a local stair manufacturer resulting in high precision, repeatable MG assemblies. SL4X The SL4X is based on a now discontinued Charvel '80's guitar. The SL4X has the Soloist body shape, maple neck with rosewood fingerboard, 24 frets, and dot inlays. The SL4X is distinct from other Soloists by having three single coil Seymour Designed Hot Rails pickups and is the only Soloist to have a pickguard. The SL4X comes in the colors of Daphne Blue, Bubblegum Pink, and Neon Orange in the spirit of the '80s. Jackson introduced Specific Ocean as an additional color in the range. External links S
