Product Description

We all spend good money on our amps/cabinets/monitors but sometimes the floor itself works against us. Speaker cabinets can interact with the floor, resulting in a loss of intelligibility. The GRAMMA is an incredibly effective device that's used to float an amp or loudspeaker and yields nearly total acoustic isolation, resulting in a purity of tone that has to be heard to be believed! GRAMMA comes complete with a carrying handle, road-ready carpet, Studiofoam Wedges (underneath) and hi-density PlatFoam. 1 or 2 GRAMMAs (23 x 15 inch) will support most amps, speaker cabinets, subwoofers & monitors weighing up to 300 lbs.

The GRAMMA is an incredibly effective device that's used to float an amp, loudspeaker or subwoofer and yields nearly total acoustic isolation. The result - a purity of tone that has to be heard to be believed!

What are people saying about the new GRAMMA?
Auralex products are unchallenged both live and in the studio. I love Auralex's new GRAMMA. Onstage it really smooths all my guitar tones. In clubs, theaters and even outdoors, the GRAMMA really makes a huge difference... The production crew of Tower of Power was so impressed, they started using them underneath the horn section monitors, the keyboardist's LESLIE speaker and several drum mics... FANTASTIC results all the way around.
Jeff Tamelier, Guitarist, Tower of Power

...Low end much more focused. I was able to dial in exactly what I wanted, w/out room resonance's.

My two recording amps stay on the stands. If we switch amps, they go right back on the stands.

All the little buzzes & rattles normally in a room go away immediately.
Lee Roy Parnell, Vanguard Recording Artist

Awesome... made all the difference in playing small rooms... Cleaned up my sound... I now enjoy my full volume tone at lower volumes.
Benito DiBartoli, Blues guitarist

Low Frequency Drum Resonance Isolation... What a concept! I recommend the PlatFoam for any drummer who needs to eliminate complaints from the neighbors or family members. I would also highly recommend it for studios that want to prevent low frequency resonance bleed. The PlatFoam is simple to use, simple in concept and is simply amazing!
Dendy Jarrett, Nashville Drummer/ MusicPlayer.com's Drum Channel Editor

Easy and inexpensive fix

What is your opinion of this product?
I went from playing on a concrete reinforced to a wooden stage, and noticed that I couldn't hear myself through the bass amp. Instead of buying a more powerful amp, I bought the Gramma instead. It works!! The bass frequencies aren't absorbed by the stage any longer, and I can hear myself clearly. I recommend trying this before investing in a more powerful amp if you're using your amp to monitor your sound.

Get the tone you want from your amp
Your general opinion of this product.
I could not get the tone I wanted from my Marshall combo amp at church. Then I started reading about bass amp coupling, where the sub-frequencies get absorbed by the floor in some settings like a hollow stage. Bought the GRAMMA, slipped it under my amp, and WOW! My amp sounds like it should. Stop fiddling with knobs and changing strings, your problem is not your gear, it is the floor!
It is a simple device and holds my MB150 perfectly. Could accommodate a larger amp or cab.

Improves the sound of every amp in a significant way
Seems ok; don't know how it would hold up after transport to years worth of gigs.
Don't know-have ha it for only a few weeks.
Your general opinion of this product.
Overall, a good product. It is decently constructed, although I find the carpeted surface a bit cheap looking.

Your general opinion of this product.
premise is sound, effect is stubtle. Do not expect a night day result.
Not a must have piece but if you are playing off a wood or hard reflective floor I ould say it would be very good to have.
Nice looking, basically a particle board on top, thick, seems strong, underside is heavy foam and a wedge baffle. It sits on a dense foam not rubber or wood.
a litle bummed it is shorter than my 4x12 cab, I expected it to hold the cab, perhap the notion was for the cab to sit flat and not be on its rubber pads or to prevent someone from not removing the casters. An air gap might ruin the dampening effect, I am guessing as to their design purpose.

heard about these from Bonamassa
Seems fort rate to me.
Seems like a wood platform to me w sonics. Cannot see why it would bend unless someone got the board wet or damp?? Particle board sort of desintigrates when wet.
Your general opinion of this product.
does what it claims allows you to get the bad off the casters and off the floor.
Gets the floor woof or reflectance off the amp interaction.
Better
Looks like a little pedal board
Cool for me, for $50 a decent gamble, I dig it

Works Great For Me
This is a really nice product. I'm surprised they can sell it for only $50.
I set my 75 lb bass cab on it and it didn't bow, so I tried sitting on the cab (I weigh 200 lbs) and the Gramma could handle it just fine.
Your general opinion of this product.
My recording room is sympathetic to A. That means when I played a low A note the whole room would rattle and quake. Problem solved.
Don't expect this to cure every problem, the Gramma is only one important part of the solution. Use the Gramma in conjunction with poper room treatment for best results. Don't rely on foam traps, get ones constructed from rigid fiberglass board like the Ready Acoustics Chameleon bass traps or similar for best results.
Tightened up the bass and decreased the "mud".
Looks great

I could live without it.
The product seems well made. It looks very nice out of the box.
I have only had it a few days but it already seems to be bowing underneath my amp. It is rated to hold up to 300 lbs but it is having trouble with my bass amp which is nowhere near 300.
Your general opinion of this product.
Overall I am a little disappointed. I really hoped it would help when playing at slighly louder volumes to eliminate some of the room noise (as advertised). It really did nothing to help.
?
I really did not notice a great difference in tone. I played my rig before I put it on it, then I played it after. A little (I mean little) less room-noise but nothing spectacular. I suppose it is not made specifically for basses but they advertised like it would make a great difference. I could easily do without this product.
Again, very nice.
Fine.
