Seriously, I too have always used "Rick" to describe the instrument and "RIC" to describe the modern-day maker. When I am only going to say it once, or am speaking to someone in person, I will say the entire "Rickenbacker" pronounced as [RICK-en-BACK-ur].
Of course, originally, it was spelled Rickenbacher and pronounced differently, but that was long before F.C. Hall bought the company I am sure. He was entitled afterwards, therefore, to change it from whatever Adolph used to whatever he darned well pleased

Do unto others as you would have them do unto you, and sit in with the band whenever you can, to keep your chops up!
