GRAMMA Isolation Risers Decouple Guitar Amps on Stage
LONDON, JANUARY 11, 2012
— Every time award-winning British blues guitarist Oli Brown plays live with his band, he relies on Auralex’s
Great GRAMMA (Gig and Recording, Amp and Monitor, Modulation Attenuator)
isolation riser to decouple his guitar amplifier from the stage. The Great GRAMMA lets Brown deliver a clean front-of-house mix without the additional boom and swell associated with non-isolated instrument amplifiers. In addition, Auralex created a custom fabric covering for Brown’s Great GRAMMA.
Brown is one of the hottest young blues guitarists on the scene today. His latest release, Heads I Win Tails You Lose, won the 2011 British Blues Award for Best Album. Legendary British blues veteran Mike Vernon, known for his work with Fleetwood Mac, Eric Clapton and David Bowie, came out of retirement to produce the album.
During a recording session, Brown discovered Auralex’s Great GRAMMA, and he tried it out. He fell in love with the difference it made in the sound of his amp. “Hearing is believing,” says Brown. “The Great GRAMMA is amazing and it is now a main part of my stage set up.”
The Great GRAMMA, patented by Auralex, is an effective isolation device that is used to float an amp or loudspeaker, yielding nearly total acoustic isolation between an instrument amp or monitor speaker and the stage. By employing a Great GRAMMA, performers realize clarity of sound that honestly represents their artistic intent. The Great GRAMMA is 30 in. long x 19 in. wide x 2.75 in. high, with a maximum weight limit of 300 lbs. The Great GRAMMA also offers a 30 percent larger surface area to accommodate popular speaker configurations that feature 4 in. x 12 in., 15 in. or 18 in. speakers.
Brown took his custom Great GRAMMA on the road with him last month for his performances in Norwich, UK and Jakarta, Indonesia. He will also be traveling with his Auralex Great GRAMMA in 2012, as he already has several shows lined up throughout the UK and France.
