Back in the early 90's when I was interning @ QUAD Recording in NY. Someone passed along an ad in Pro Sound News, for this.
All of us were excited. Finally, no more lugging around heavy amps and racks of 2290's, Drawmers, and Ultra Harmonizers. This would be a producers dream come true.
But alas. These were lofty goals. And the technology just wasn't up to par yet.
Fast forward to now....
This actually works.
Buy one. I'm sure glad I did. Kthxbye.
