The above Byrds Rickenbacker headstock photo was made available to the Rickenbacker Registration Page by Tomcat. The closeup of this Model 370/12Byrd headstock shows the twelve full-size gold-plated Grover keywinds installed by McGuinn in 1969, six of which he mounted upside down on the sides of the headstock. The Rickenbacker logo on the truss rod cover is a classic feature of this historic instrument.
