What We Think

The Mesa Boogie Triple Rectifier has become a new classic for those players looking for extreme tonal versatility across all genres and playing styles. From bold cleans to spongy overdrive all the way to blistering high gain territory, and all sorts of tweakable settings in between, the Triple Rectifier just about does it all...and does it all LOUD.

As much as the Triple Rectifier offers, though, some players need a little...MORE. And more is what the wizards at Voodoo Amps did. With a push/pull gain boost, an upgraded Voodoo-Designed Output transformer, and a host of other modifications, this amp is set to blast you off into space. We were all impressed with the improved low-end response and lightning fast articulation on all of the channels. Those Voodoo Amps guys definitely know what they're doing!

Check the specs on this one for more details on the modifications. This is what a Triple Rec was born to be! 

Manufacturer's Description from Mesa Boogie


It’s been over twenty years, two generations of guitarists and several musical trend-cycles since the Dual Rectifier® first unleashed its crushing wall of gain on radio. The Triple Rectifier® takes the world famous platform to a new level of power dominance.

A decade ago both of our famous Recto®’s underwent a massive facelift that greatly expanded their versatility, moving from 2 Channel amps aimed squarely at high gain only – to 3 Channel amps capable of roaming any style confidently. Still delivering the widest, deepest footprint in heavy music, both the Recto®’s now serve a long list of chart topping devotees both in and outside the world of heavy.


The Triple Rectifier's Channel 2 and 3 Offer RAW, VINTAGE HIGH GAIN or MODERN HIGH GAIN Modes

Each channel on the Triple Rectifier features independent wattage controls quickly accessed via the second two-position mini toggle on each of the amp’s three channels. The Recto®’s Multi-Watt™, channel assignable power amp (Patent 7,602,927) allows each channel to be independently set at 50 or a crushing 150 watts of power. Essentially you now have the power to harness either 2 or all 6 power tubes to each channel for power ratings of 50 or 150 Watts of class A/B power via the independent 50/150 Watt Power Switches.

Tube compliments include 6x6L6 (or 6xEL-34), 5x12AX7 and 3x5U4. Our Bias Select switch (6L6/EL34) offers Fixed Bias for consistent, maintenance free performance.


We’ve unearthed a lot of secrets in the last two decades and we’ve used them all in this latest rendering of the Triple Rectifier®. 8 sound modes across 3 channels are now on tap. The improved CLEAN and PUSHED sounds found in the Triple Rectifier's Channel 1 are based on the popular Lone Star® and Mark V® and offer a full-bodied, well-balanced clean signal - a perfect starting point for shaping your ideal clean tone.

MESA/Boogie®’s contribution to modern heavy rock and metal cannot be denied. On the lower end of gain, in both Channels 2 and 3, RAW mode offers an excellent classic-rock style sound. A smooth progressive transition away from the higher end of RAW, VINTAGE takes over offering a fluid tonal transition headed straight toward metal mayhem. Channel 3 delivers a wish list of what heavy aficionados might expect from the original engineers of cascading gain. Switching from VINTAGE to MODERN, fuels an inferno with increased low end, a boost in the high Mids and an aggressive bite unlike any other.


The SOLO and OUTPUT knobs on the Triple Rectifier are only active when the FX Loop is engaged. The SOLO knob adds extra boost for lead work, and it can be activated anytime quickly via the SOLO button on the footswitch. The OUTPUT knob controls the overall amp volume, and it’s ready for action after you have balanced every channel’s GAIN and MASTER volumes to meet your taste.


Each Channel features Multi-Watt Power Switch (50/150 Watt), Independent Gain, Treble, Mid, Bass, Presence, Master, Channel Assignable Dual Rectification with Recto Tracking™ (Diode or Tube Tracking Patents 5,168,438 & 7,193,458). Tube Tracking further compresses sound in a very clean subtle manner. If more headroom is needed, Diode rectification is an alternative option for tighter low-end tracking.


Our footswitchable, fully buffered FX Loop features two jacks (Send and Return), a Send Level knob, and a five-position rotary Assign control (for bypassing the loop or assigning it to any or all channels) allowing seamless integration with outboard effects processors from the Recto’s footswitch.

Experience our Triple Rectifier®, the king of heavy, at a Dealer near you and feel for yourself the incredible sonic power and versatility of this world renowned icon.

About Manufacturer

Forty-five years and thousands of satisfied customers later, MESA/Boogie® Ltd. hand-builds the fifth generational offspring of that pivotal amplifier (and many more) now known around the globe as the MARK I Boogie®; the world’s first high gain, high power, compact 1x12 amplifier. That revolutionary little combo is the “missing link” in amp design... the pivotal nexus between Vintage and Modern guitar amplifiers. When it comes to amplified guitar, there’s really just two epochs… before Boogie, and after Boogie.
