is a 12'x11' bare concrete room in Enshede, Holland.

Seriously. I just pulled out the horn to blow a bit last night, and even with a mute in, it made me sound like I was in Carnegie Hall. No joke. Now I wish I'd brought my laptop and audio interface and a kickass mic to record myself. In fact, since this magic reverb room happens to be in the apartment that my sister is renting, I may go home and send her some audio files and have her set up a speaker in one corner of the room and a mic at the opposite corner, record it, and send it back to me. Or just make another trip back. Like she said, a $400 round trip ticket is cheaper than renting out Carnegie Hall
