I don't normally paste quotes from Wikipedia, but I ran across this today and thought it was worth sharing.
The Rode NT-1A is a popular starter condenser among home recordists - I have one - and one of the first of the Shanghai-manufactured microphones. It's a decent mic for not much money. I'd always wondered about the odd spelling of the company name "Røde", so this morning I decided to look it up. Here's the story...
Sales of the modified microphone began to take off in Sydney, which (in the Australian vernacular) was likened to “a rat up a drain pipe”. This gave lend to the unofficial title the ‘Rodent-1’, which was later broken up to become the RODE NT-1. Peter Freedman dropped in the ‘Ø’ character as a salute to his Scandinavian heritage, and Rode was born.
The Swedish connection is that Peter Freedman had grown up in Stockholm, although his parents were British.
