Auralex GRAMMA™ Isolation Riser

The Auralex GRAMMA (Gig & Recording, Amp & Monitor, Modulation Attenuator) is an incredibly effective device for floating an amp or loudspeaker and yields nearly total acoustic isolation, resulting in a purity of tone that has to be heard to be believed! GRAMMAs are incredibly effective with guitar & bass amps, PA stacks, and subwoofers.

Auralex GRAMMA comes complete with a carrying handle, road-ready carpet, Studiofoam Wedges (underneath) and PlatFoam (underneath). 1-2 GRAMMAs will support most amps, speaker cabinets, subwoofers and monitors. An optional Gigbag is also available.
