"
DiMarzio Inc. cite the Super Distortion as being introduced in 1972, but I’m not really sure what kind of introduction this would have been. Initially, Larry DiMarzio was selling only to friends, and this progressed to a mail order operation before any sort of major distribution system was set up. No timeframe is given for the progression, even in printed matter from three decades ago, and DiMarzio themselves provide virtually no published info on the company's early life. However, even as late as 1974, DiMarzio’s pickup production was evidently very limited, and if you actually try tracing any DiMarzio pickups made prior to ’74, there’s a distinct absence of any credible claims of ownership."

.. also vermutlich so, als würde man behaupten, es gäbe Les Pauls schon so lange Paul an E-Gitarren rumexperimentierte

Aber schon erstaunlich, wie wenig einheitlich die Aussagen da bei einem doch recht etablierten Hersteller der Neuzeit sind ... kein Wunder, dass wir da so häufig im Halbdunkel tappen ... letzlich ist ja jeder auf seine eigene Recherche und das Ausmaß der ihr zugemessenen Glaubwürdigkeit angewiesen ...
