I love my Gramma!

[StrangerDanger]

Just wanted to profess my undying and eternal love of the Gramma GRAMMA Isolation Riser - Acoustic sound isolation products from Auralex Acoustics..

You cant find a better sound improvement for $55 anywhere. I put my 210/212 stack on this thing and I found several improvements:

• Tighter lows.
• More expressive highs.
• Greater efficiency.
• Looks cool too.

I have been more into a scooped tone lately with lots of lows and highs but I couldnt get this tone to be loud enough in the mix without getting mushy and losing note articulation. Thats all gone now. I can crank the bass knob (not that I would) and still hear each note in a fast run. I can run my amp with the master volume 2-3 notches below where I was running it before and still get the same loudness. And the drummer actually says he can hear the highs now, .

Anyway, I dont usually gush over gear like this but GRAMMA really works well and I cant imagine why more people dont use it. You wont believe how much of your tone and volume you are losing to the floor. Why give it away to the floor when you can put it in somebody's earhole?

Nobody else loves their Gramma?

This is not meant to dispute your results or your satisfaction with the product, but I think you'll find that $5 worth of rubber feet will accomplish the same thing acoustically, but I won't argue about the cool factor. It's a nice looking piece of kit.

Remember, the GRAMMA is only mechanically decoupling your cab from the floor. You would need to raise your cabs at least 2 feet off the ground to acoustically decouple them.

But all in all it's a good product as long as you understand what it really can and cannot do.

Cheers

All I know is what I hear. I wanted to think it was bunk until I actually tried it. In my case, hearing was believing.

I have no experience with the GRAMMA but I like this quote so much I may have to sig it!

Please don't think that I'm saying it's bunk...I'm just saying that the effects are the result of mechanically decoupling your cabs from the floor and the same thing can be accomplished in other ways.

Yes, this is totally sig worthy.

I've got one and I love mine too!! Not so necessary on a concrete stage, but it's magic on any kind of hollow stage. The cheesier the stage, the bigger the difference.

[gjbassist]

So what other methods could be used to decouple a cabinet from the floor to get similar results?

[Stumbo]

There were a couple of threads on this topic....yeah, there they are....might be worth checking out.

Isolating Head/Cabs from stage/each other Amp/Cab stands

[phatbass]

Anyone know the type of foam used in the pads? They're only cheap, I know, but it looks like a project for me to mess around with...

A pair of cinder blocks would get it done. If you wanted to build something like the Gramma you could do it with a sheet of plywood and 4 hockey pucks.

I have a Gramma that a guy threw in with the amp I bought from him (moved out of state and sold all his gear). I've also enjoyed using it. Like CindyB said, it's especially good on a hollow stage: keeps it from turning into a giant subwoofer.

Thats exactly right. And my house is pier and beam construction, so just practicing at home its helpful as well.

No worries, I knew what you meant. What I'm saying is that I actually thought it was going to be bunk and was very pleasantly surprised when it wasn't.

Both me and all my band mates are VERY happy with the results I get with my Gramma pad. I use a NV215 on it. It gets a little tippy- not too bad, but I always use it now and I can really dig in without any complaints. Before I always was told to turn down- too boomy, etc.

[rapidfirerob]

Like mine as well on hollow stages.

[uhdinator]

I use 2 gramma's under each 215 sub when at a location with floors that can resonate. Every little bit helps for more defined / tighter LF.

While experimenting with a mic/desk stand on my wood puter table I could hear rumble in the mic from the puter and drives running with a less sensitive dynamic mic even.

This is why when mic'ing amps live its also a good idea to put something under the mic stand, and don't use cheesy devices that attach your amp mic to the cabinet/amp. Have had to use a wet bar towel in a pinch and it helped quite a bit. (could hear footsteps in the amp mic as the steel round base was on a hardwood floor and had no rubber feet on it)
