Build a better mousetrap and the world will beat a path to your door. For guitarists, that better mousetrap arrived in the early ’70s when Keith Barr gave the world the MXR Phase 90. It was the first of many brightly colored effects pedals that would find their way onto stages and into recording studios worldwide.
Barr and his partner Terry Sherwood owned an audio repair shop in Rochester, New York, where they were shocked by the poor quality of the guitar effects their customers brought in. Barr and Sherwood decided they could give guitar players a better sounding, cooler looking, and more reliable stompbox. MXR was born, and the company gave guitarists access to amazing sounds—some of which were previously available only in high-end studios—delivering those sounds in rugged, roadworthy enclosures.Load More
The response was immediate and overwhelming. Starting with a few dozen Phase 90s constructed in a basement and sold out of a car at gigs, MXR added three more pedals to the core lineup: the Distortion +, the Dyna Comp® Compressor, and the Blue Box ™ Octave Fuzz. Soon, the growing company was cranking out thousands and thousands of stompboxes and distributing them all over the planet. Guitarists everywhere were plugging into MXR pedals, and those chains of multi-colored boxes became synonymous with out-of-this-world sounds and limitless possibilities.
The long list of timeless recordings that feature MXR pedals includes classic tunes by such giants as Led Zeppelin, Van Halen, the Rolling Stones, and many, many others. The vicious distortion on Blizzard of Ozz? MXR Distortion +. Jimmy Page’s “Fool in the Rain” solo? MXR Blue Box. Virtually every song on Van Halen I? Phase 90. Keith Richards’ trippy tone on “Shattered”? Phase 100. The intuitive operation and bullet-proof reliability of MXR pedals ensured that those guitar heroes could reproduce the sounds of their hit records night after night on the road as well as in the recording studio.
The music business can be fickle, however, and MXR’s fortunes would shift in the ’80s as other manufacturers began to catch up. MXR closed its doors, but the core products never fell out of favor. Jim Dunlop recognized this, and acquired and resurrected the MXR brand. Fittingly, Dunlop’s first MXR releases were the Phase 90, the Distortion +, the Dyna Comp Compressor, and the Blue Box Octave Fuzz. Dunlop’s acquisition meant that guitarists could once again get their hands on the classic MXR effects, and it also represented a continuation of Keith Barr’s innovative legacy with the eventual release of many new designs.
Pedals such as the Carbon Copy® Analog Delay, Custom Badass ’78 Distortion, and Smart Gate® Noise Gate have become modern classics. The Bass Innovations line offers bass players pedals designed with their very specific needs in mind, and the MXR Custom Shop serves as a testing ground for the MXR team’s most ambitious and adventurous ideas.
What’s more, the MXR roster now includes classic non-MXR effects such as the Talk Box and the Uni-Vibe Chorus/Vibrato—recreated with dead-on accuracy and imbued with all the qualities that made MXR famous—in addition to several signature effects developed in conjunction with guitar players such as Eddie Van Halen, Slash, Zakk Wylde, and Dimebag Darrell.
The 40th anniversary of MXR’s incorporation finds the company more vibrant and exciting than ever, offering dozens of models for guitar players and bass players, with the time-honored effects that got the company started sitting proudly alongside forward-thinking boxes never dreamed of by the founders.
The fact that we can’t remember a time when there weren’t hundreds of stompboxes to choose from is due in large part to MXR. The company’s first print ad, which appeared on the back cover of Rolling Stone and featured the then-unheard-of Phase 90, stated simply, “MXR: We Are Here.” Those words are far truer on the 40th anniversary than they were when they were written. The next 40 years will only bring more incredible sounds in neat little boxes to innovative musicians everywhere as the company that created such a big part of the soundtrack of our past provides the tools to take music into the future. Prepare to be amazed all over again.
