Gibson. Gibson US-1 (1986–1991) – first Gibson mass-manufactured try at the superstrat market Gibson U-2 (1987–1992) – second Gibson's superstrat, a somewhat stripped down version of US-1, featuring basswood body without a figured top, dot inlays, and regular pickups. Gibson Q series Gibson M-III (1991–1994; reissued 2013) End of superstrat era In early and mid-1990s, heavy metal and particularly shredding declined in popularity, in favor of grunge, nu metal, alternative metal and other styles. The popularity of superstrats also declined, in favor of guitars more suited to these new styles. Companies that relied on superstrats as a major part of their target market suffered heavy losses and went out of business or were bought by larger corporations: Guild exited the solid-body guitar business in 1988 and was acquired by Fender in 1995. Hamer was acquired by Kaman Music Corporation in 1988, which in turn was acquired by Fender in 2008. , Hamer reduced their superstrat selection to just one model, the Californian. Dean was sold to Tropical Music in 1990. Superstrat production was resumed by its new owner in Korea. Kramer went bankrupt in 1990 and was sold to Gibson in the early 1990s. The Jackson and Charvel brands were bought by Fender in 2002. Ibanez suffered heavy losses in 1991–1993 and had to undergo a major restructuring of its model lineup, adding such series as the GR ("Ghostrider"), Blazer, TC ("Talman"), RT ("Retro") guitars, and TR ("Traditional") and ATK basses. The older Iceman model and Gibraltar bridge were resurrected as part of the new "vintage" theme. This restructuring kept the company afloat, tweaking its image from a "metal guitar only company" to a more customer-appealing one. Nevertheless, extended-fretboard superstrats remain popular among metal and shred guitarists in particular, and are produced by guitar manufacturers of all sizes. Additionally, some Stratocaster modifications which were strongly associated with the superstrat, such as the Floyd Rose tremolo system and especially the inclusion of humbucking pickups, have become widely available from stock on 22-fret bolt-on neck instruments which are often seen as Stratocaster variants rather than superstrats, including several stock models of official Fender Stratocaster. A Fender Stratocaster mounted with at least one humbucking pickup (usually a single humbucker replacing the bridge pickup) is often called a "Fat Strat." The available Fat Strat configurations as of 2018 are HSS (all models including both Fender and Squier), HSH (Player and MIM Deluxe only) and
