The Auralex GRAMMA™ v2 (Gig and Recording, Amp and Monitor, Modulation Attenuator) is an incredibly effective patented device that's used to float an amp or loudspeaker. This highly effective isolation platform features an Ozite® covering over an inert structural layer that floats on a 1” pad of acclaimed Auralex® Platfoam™. This carefully engineered studio and live performance solution allows the true sound of your amp or loudspeaker to come through by negating resonance artifacts that can muddy up the tone of your amp.
