Explore Neural Amp Modeler (NAM) profiles of the legendary Mesa Boogie Dual Rectifier, the high-gain monster that defined modern metal and hard rock tone. From the original 2-channel Rev F and Rev G to the expanded 3-channel models, this iconic amp delivers massive, crushing distortion with thick, saturated sustain and bone-crushing low end. Used by Metallica, Dream Theater, Foo Fighters, Linkin Park, and countless metal acts, the Dual Rectifier's switchable tube and silicon diode rectification, multiple voicing options, and aggressive midrange scoop have made it the go-to amp for brutal rhythm tones and soaring leads since the early 1990s.
