Mesa/Boogie Rectifier

[2] Hard rock and metal guitarists increasingly sought heavier tones by the late 1980s, and many guitar techs, like Michael Soldano and Reinhold Bogner, turned from modifying amps to building their own boutique models to satisfy demand.

Faced with this increasing competition, Mesa/Boogie began developing a new, higher-gain model of their own in 1989, dubbed the "Dual Rectifier" in reference to its use of both tube and silicon diode power amp rectification.

[2] Guitarists across a wide swath of rock genres quickly adopted the Rectifiers, including artists in grunge (Alice in Chains, Soundgarden), alternative (Foo Fighters, Bush), punk (Bad Religion, Blink-182, Sublime), and metal (Metallica, Tool, Rammstein).

[8] In 2000, Mesa/Boogie switched from the original two-channel Rectifier designs to three-channel versions,[2] which remained in production until early 2010, when they were superseded by the current Multi-Watt models.

It was intended to look threatening compared to the brand's earlier Mark series amps, and to that end featured a diamond-patterned tread plate as a front panel, with metal knobs and black leatherette covering.

[2] Revision G became the most widely used version, with Guitar World describing its massive, tight low end, throaty mids and super-saturated gain as the Dual Rectifier's signature sound.
