Auralex GRAMMA Acoustic Pads

[Sean]

Are these Auralex pads any good?

Gimmick or really useful piece of kit? Does anyone have any experience of these?

I've got one that I've used for recording sessions - to isolate a bass cab & guitar combos. They certainly do work & are very effective at reducing the amount of low frequencies from being transferred through the floor & tightening up a bass / guitar sound. And we got some great results with guitar combos. Though you may find that the bass sound you get is something of a disappointment - as it can make a bass cab sound like it's lacking in bass response (personally, I love feeling the whole room rumble!).
There's [url="http://basschat.co.uk/index.php?showtopic=7949"]another post here[/url] about them - I think people have had good experiences using them to get a better live sound on 'boomy' wooden stages...?
Definitely a 'try before you buy'.

Yep, I've got one and I use it, as 99ster says, when I'm playing on horrible, hollow, wooden stages. Depending on the situation, I find it either has very little effect on my sound or it makes a huge difference so it's a case of 'try it and see' for me. It takes up no room in the car so I tend to take it everywhere just in case but i would recommend getting one for sure.

I've got one. Always take it and use it whenever playing on a hollow stage. Cuts out the boom and helps keep a nice tight sound.

I've got a platform that I made using the same foam used on the Gramma boards (and when I finally get my ass into gear, I've got to make another one... ahem :blush: ). Perfect for hollow stages, stops any complaints dead in their tracks.

Why not try a thick rubber door mat, less then a fiver from Tesco

Cos it sounds better?

I use mine where I know there is a boomy stage. It works.

Do tell - what is the foam used, then?

[dave_bass5]

How does the sound change out front when using one of these pads?
Ive thought about getting one in the past as i play on a lot of hollow stages and it can get boomy but once off the stage i find the low end dies off pretty quick. Thats the reason i dont elevate my cab as the low end seems to dissapear.
Does using one of these pads mean that you can turn the low end up without it getting boomy?

Like others have mentioned, I use mine to kill the boom on hollow stages. There may be a slight loss of bottom end, but it is more than made up for by the increase in clarity.

They do seem expensive for a slab of particle board with some foam stuck on the bottom, but they work!

Cheers Chris.
Yes, they are expensive though. For me its the size that would be a problem as our car is pretty full.

Hey Rich, Spill the beans, What's the foam?

[bass_ferret]

Its sold by the same shops that sell the Gramma pads and is made by the same firm.

Auralex PlatFoam. About £10 per strip from Studiospares, cut it into two strips the width of your cab, place one under front edge and one under back edge. Throw strips in bass gigbag to transport. For tiltback, don't use the back strip or for extra tilt place both at front. I have been saying this for years but it keeps flying under the radar...

Alex.

Can i ask if this is still as effective if the cab has feet?

whats been putting me off getting this stuff in the past is the wooden platform part. if i can just put the strips of foam under my cab i think ill give it a go.

Cheers.

Check out Bass Direct. Mark is now stocking Auralex Gramma isolators and at a better price than Studiospares.

The foam is about 4"x2" so I can't see feet being a problem.

Note that although this mechanical isolation will stop cab vibrations going into the stage it will not prevent acoustic output from your cab from vibrating the stage. Furthermore a well designed cab should vibrate very little from its own vibrations. However I do find the tilt aspect rather useful.

thanks Alex. at that price i might as well give it a go.

My1212L seems to be quite at home on a wooden stage compared to my older cabs but it can still get boomy of course.
Those strips are just the right size.

They are the perfect size for my 1212L. Does anyone know if they fold up (stupid question i know but thought i would ask)

[poptart]

The feedback I have had from my customers is very impressive, although probably not necessary for all gigs I think these are the answer for those hollow stages and boomy rooms that crop up.

Hi everyone!!
Definately work in boomy hollow rooms, have found it tightens th sound and any loss of bottom can be EQ'd but at least you have that option, love mine and use it for all gigs, but you.d probably not tell the diffrence in a good room.
Bass directs price is fantastic i paid £70 (with postage)for mine about 3 years ago, well worth a try for the cash, in fact i fancy the big one all the best-lee

That price is VERY good - I paid more than that for a used one off eBay - that I got for a 'good' price compared to anywhere selling them new!

How many years has it been now?

[birdy]

I bought one of these from bass direct about 3 weeks ago and have used it on about 4 gigs, 2 of which had very boomy wooden stages and it certainly made enough of a difference to my ears to justify the price and lugging it around. I will take it to every gig now. It didn't completely solve the boominess but it definately helped from my experiences to date.
