Gig & Recording Amplifier & Monitor Modulation Attenuator
The GRAMMA Sound Isolation Riser is an incredibly effective device
that's used to float an amp or loudspeaker and yields nearly total
acoustic sound isolation, resulting in a purity of tone that has to be
heard to be believed!
Built on the success of GRAMMA, the Great GRAMMA is almost 30% bigger to float large speaker cabinets.
Now 4x12s, 15" or 18" speaker cabinets will benefit from the awesome Great GRAMMA.
Only Great GRAMMA can handle the big rigs!
GRAMMA and Great GRAMMA both come complete with a carrying handle, road-ready carpet, Studiofoam Wedges (underneath) and PlatFoam (underneath).
