Tonex MESA/Boogie Reference

The amps that defined modern guitar tone

The MESA/Boogie Reference Signature Collection for TONEX gives you instant access to 5 one-of-a-kind amps.

All of these era-defining amps have withstood the test of time with their sonic mojo and feel, many featuring components no longer available. Located in MESA’s Tone Lab these “reference amps” are essential to maintaining historical accuracy, while providing invaluable insights to shape future designs and guide the MESA legacy forward.

Now TONEX lets these icons escape the lab to rock the world again.

All 5 amps were fine-tuned to their sweet spots by legendary “Tone Boy” Doug West, MESA’s in-house tone guru for over 40 years, in a range of styles from Metallica-esque Mark IIC+ tones to Santana-inspired singing lead tones. Meticulously captured with IK’s Advanced AI Machine Modeling Technology at a world-class studio in Northern California, the results are an unparalleled collection that you can own today.

What is a reference amplifier?

A reference amplifier epitomizes sonic excellence, embodying the essence of its unique design and sound. They aren't prototypes, but production models that were recognized as being exceptional, and then were meticulously scrutinized component by component to unlock the secrets of their sonic brilliance. These amplifiers perfectly represent the Series and are the gold standard for their model and sound, as well as for shaping the sound of potential future amplifier designs.

The Best of MESA

The MESA/Boogie Reference Signature Collection features four iconic Tone Lab amplifiers: a 1984 Mark IIC+, a 1989 Mark IV, an early ′90s Dual Rectifier (dual channel) and a 1994 Triple Rectifier (dual channel). As a bonus, we’ve also included a limited-edition King Snake, an exact recreation of Carlos Santana’s original “Budokan” Mark I which, as he says, is “built to make pretty notes.”

Reference cabs

Two notable reference cabs were used to capture the thick rich tone of the 4 MESA reference amps. These cabinets have been used by Randall and Doug over several decades and offer a unique “broken in” experience that’s smooth, dynamic and touch sensitive. The King Snake combo is loaded with a Jenson Blackbird 100 Alnico for a warm, clean and singing vocal-like quality when turned up.

Doug West “Tone Boy”

Doug joined MESA in 1981 as a Sales/Product Specialist, swiftly earning the nickname "Tone Boy" for his collaboration with Randall Smith in R&D. With a deep passion for guitar tone and a rich history in the Bay Area music scene, Doug ensures every Boogie® product resonates with soul and excellence. He played an integral role in capturing the MESA/Boogie Tone Models and his ear, passion and insistence on “vibe and feel” were critical in the creation of the models represented in this truly unique collection.

The MESA/Boogie Mark IIC+ is revered by guitarists for its legendary tone, versatility and build quality. It has left a significant mark on the world of guitar amplification and continues to be sought-after by musicians seeking iconic rock and metal tones.

The Mark IIC+ amp has graced the fingers of many top artists and studio players such as James Hetfield, John Petrucci, Steve Lukather, Neal Schon and many more.

This amp was dialed in to bring out its best qualities and most useful settings to cover a wide range tones and genres. Included in the collection are captures with the infamous “V” curve graphic EQ setting as well as amp-only captures to add your favorite impulse responses.

Similar in character to the Dual Rec, the Triple version has 150-watts on tap for a tight low end with a bit more punch and clarity.
