The Dave Brubeck Quartet
"it was a tremendous relief to know that we never had to worry about the piano being heard. The technicians at the White House were equally impressed with the way everything sounded...."
Russell S. Gloyd
Producer

Montreux Jazz Festival - 1997
"I personally engineered 90% of the bands and artists who appeared at Montreux - without the C-ducers the grand piano could not have been amplified at the volume required nor would it have sounded as natural and as dynamic as it did. Many thanks again."
