Unrivaled Headroom, Pure Authority, and 3-Channel Versatility

The Mesa/Boogie Multi-Watt Triple Rectifier 150-Watt Head represents the ultimate evolution of the iconic high-gain amplifier platform that redefined rock and modern metal. Delivering 150 watts of Class A/B horsepower across a six-6L6 power section, this updated Multi-Watt version expands the original Rectifier's legendary aggression into a flexible, 3-channel studio and stage centerpiece.

Featuring Mesa's patented Multi-Watt™ Channel Assignable Power (Patent 7,602,927), each channel can be independently assigned to run either 2 power tubes (50 Watts) or all 6 power tubes (150 Watts). Channel 1 incorporates pristine, full-bodied Clean and Pushed voicings based on the legendary Lone Star® and Mark V® circuits, while Channels 2 and 3 offer RAW, VINTAGE, and MODERN High Gain modes. Combined with patented Recto Tracking™ (Tube or Silicon Diode Rectification) and global SOLO volume boost controls, this Triple Rectifier provides unmatched tracking speed, crushing low-end impact, and pristine clean headroom.

The Sanctuary Perspective: There is simply no substitute for the sheer acoustic displacement and note-tracking speed of a Triple Rectifier running at 150 watts. The Multi-Watt update is the sweet spot for this circuit—dropping Channels 1 or 2 down to 50W allows you to sweeten the power section feel for blues and hard rock, while switching Channel 3 to 150W Diode tracking gives you tight, instantaneous low-end punch for aggressive styles. This pre-owned unit (SN: R-053606) is in Excellent condition and includes its original footswitch, cable, and fitted cover.
