C-ducer was invented back in the 1980s by a musician, a physicist and an engineer. The original application was for miking Latin drums. When you are playing congas and bongos together there isn’t much room for conventional mics so the inventors came up with a micing system that mounted internally, could withstand the sound pressure level inside a drum, and had a studio quality sound.
It transpired that the C-ducer outperformed most other mics in many more applications than Latin drums. When Frank Sinatra started to use it on piano (in fact, would not go on stage without it), along with Moody Blues’ drummer, Graeme Edge, John Williams on guitar, and a host of other well-known musicians, the world of live sound production started to take notice. When Dave Brubeck toured Russia (amazingly just a few weeks after bypass surgery) he credited C-ducer on the album cover and claimed that he “…could not have recorded the album without C-ducer.”
Later many famous venues started to use C-ducer - The Royal Opera house used it to mic gongs and later piano, likewise Sydney OperaHouse, the Royal Albert Hall, Radio City Music Hall and many others.
As well as sound quality, the C-ducer was embraced because of its ability to reject the sounds from other instruments, its incredible dynamic range and its immunity to feedback compared with conventional mics.
