Fender Super Reverb Master Volume

[jy67]

Anyone know of a layout for the Super Reverb with the push-pull master volume?

What's the actual designation for that circuit?

Thanks -

A chap with the username Ten Over has documented the layouts for later 70s Fenders.
I suggest to search for posts from him at this forum or TDPRI.
He hasn't frequented this forum for about 3 years.
