The battery plates on those say they were built for a Greg Lake.....
...and Sold!
(That's good 'cause I was just thinking how nice a series 12 string with mojo would be.)
Any idea what year those were made? The seller spoke of a bass as part of this group, was it customized as well? Was the six string a standard series II, or was it customized like the twelve?
Nice group of instruments, though it's probably a good thing they sold before I saw it "no, ma, don't worry, still got enough for your iron lung, honest!"
