Looking for to record “rock drums”? Just put them close to this wall. Ha ha Seriously, that is a tuned stone diffusor. I'm not sure how that works.? I remember our guide explaining to use that they used a 100,000,000 concrete trucks to pour the walls which are nuclear safe or something...seriously they are supposed to be nuclear safe.

Here's Dan Huffs Pro Tools Controller. Dan Huff has produced everyone from Megadeth to tons of country.? He's about as big as you can get.?
Here is an Elam or Telefunken (I'm not sure) stereo 251 prototype. There are like none of these in the world. The mono 251s can go anywhere between $10,000 and $30,000 and are not THAT hard to find. On the other than, there are like 2 of these.... ever. If I remember correctly, our tour dude estimated that the mic was worth $100,000.
