fixed bridge. The SL2H-MAH is made of mahogany (neck and body "wings"), with a transparent paint finish on both body and headstock. All SL2Hs are made in the US. The SL2 is again a USA made Soloist with neck-thru construction (all Soloists have neck-thru constructions). The SL2 can be considered a more modest version of the SL2H, made up of maple thru-body neck and poplar wings, with an ebony board and "optional" sharktooth inlays. Most of them had a plain fingerboard without inlaid markers on it. The bridge is Jackson's Floyd Rose-licensed double locking tremolo JT-580 which is widely used on Japanese-made Jacksons. The Jackson logo is not "mother of pearl" on SL2s while it is on SL2Hs. The USA-made Soloist SL2H and SL2 were discontinued as production instruments in 2021 to make way for the Japanese MJ Series Soloist SL2. SL3 The SL3 belongs to Jackson's Japanese-made Pro Series guitars. The body is made of alder and includes a flamed maple veneer on transparent finish models. The SL3 features the traditional Soloist setup of two single-coil slots for the neck and middle positions and a hot humbucker in the bridge position. Seymour Duncan Hot Rails are fitted in the single-coil slots and a Seymour Duncan JB humbucker occupies the bridge position. Additional features include an FRT-02000 or JT-580 double-locking tremolo, 24 frets, a compound radius Rosewood fretboard, sharktooth inlays and matching headstocks on transparent finish models. Jackson SL3s are manufactured in Japan. There is also a newer MG-version of it, SL3MG, which has the same features but with EMG 81/85 set. The Pro Series SL3R, made in China, features a mirror with matching reverse Jackson pointed 6-in-line headstock, white body binding and chrome hardware with 12"-16" compound radius bound ebony fingerboard with 24 jumbo frets and mirror piranha tooth inlays. In September 2022 Jackson released the American Series Soloist SL3. Made in Corona California, it comes in Gloss Black, Platinum Pearl, Riviera Blue or Satin Slime Green finishes with color matched Jackson pointy headstocks and black hardware. SL4 A very high quality Japanese manufactured model came to the market from the year 2000 until 2002 - the SL4 and it was from the high models of the Jackson guitars as they were made from alder or mahogany for the body-maple or mahogany for the necks but with two differences from the SL1 or the SL3 of Japan that were
