Mesa Boogie Dual Rectifier - Modern preset

Verified · 85/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Dual Rectifier is arguably the most influential high-gain amplifier of the 1990s, defining the sound of alternative metal, nu-metal, and hard rock for an entire generation. Its selectable tube or silicon rectification delivers either a tight, punchy response or a slower, saggy feel, while three channels span from clean headroom to extreme saturation. The Dual Rectifier's thick low-end, scooped midrange, and wall-of-sound gain became the sonic benchmark for heavy music worldwide.
