It's hard to say "one off" and Rickenbacker in the same sentence anymore. WOW! This being a '79 4001 explains why it doesn't have the blackened hardware as that didn't come around until 1985 (possibly late '84), but what is unusual about this is that the NECK has black binding. Most 4001 that have black binding have it on the body only, with white binding on the neck. But "never say never" and here is the proof. And a lefty at that. Fireglo with black binding is unusual enough. WOW!
