Auralex GRAMMA Test

I'm sorry out of tune. I am similar to the sound that on-mike recorded.

The height of the amplifier has changed in 1:29 seconds. I put it on GRAMMA. The sound changes, too.
I didn't think anyone would notice such a clear difference. I should have been a little more kind. Sorry.

I think he adds the Gramma @0:45 or so - you can see the amp get higher compared to before the cut. But the camera mic is doing the recording and since the amps position changed, so does the tone so really hard to compare.

Is this a joke video? The Gramma is suppose to go UNDER the amp!
