I've been searching the 'net for the schematics for the electronics of the Jack Casady bass for some time now. And come up with nothing! Gibson's got a lot of info on all their basses - except this one....
Does anybody have any info, like a schematic or some picture? (rather intreaguing to think of how somebody might have taken such a picture

)
Why I want it? Well, I was thrown over by the impressive sound variation and the apparent simplicity of the controls - but I never really got how it is achieved!

Please, if you can help, please do!
