Built on the success of the GRAMMA™, this GreatGRAMMA™ v2 acoustic isolation platform is almost 30% bigger to float large speaker cabinets. Now 4x12s, 15 in. or 18 in. speaker cabinets will benefit from the awesome GreatGRAMMA.

The GreatGRAMMA™ v2 (Gig and Recording, Amp and Monitor, Modulation Attenuator) is an incredibly effective patented device that’s used to float a speaker cabinet, amp, or loudspeaker. This highly effective isolation platform features an Ozite® covering over an inert structural layer that floats on a 1 inch 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. GreatGRAMMA yields nearly total acoustic isolation, resulting in a purity of tone that has to be heard to be believed!
