The Great GRAMMA (Gig and Recording, Amp and Monitor, Modulation Attenuator) is an incredibly effective patented device that's used to float an amp or loudspeaker.
Have you ever put your amp on a hollow stage and had problems with controlling low end rumble? Great GRAMMA is for you....
Great GRAMMA yields nearly total acoustic isolation, resulting in a purity of tone that has to be heard to be believed!
Get a more consistent tone from your amp from place to place, gig to gig, by using the Great GRAMMA, as your amp is on a consistent surface. You'll also notice a tightening of your low end response, and more overall clarity from your amp.
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!
