December 12, 1980 4-bolt guitar neck plate drawing...

From a post on CLF Research facebook page (12/21/2023):

December 12, 1980-I remember back in ‘97 when we started phasing in 4-bolt guitar necks. Heresy! Leo would be rolling in his grave!
Yeah, well, Leo might be offended by that as he was considering doing the same for 1981+ models. Don’t think I ever showed you guys this.
There’s a bass version too.

Thanks Craig, very interesting bit of history.

I may have to retract statements made in the past. maybe..
