The topboost was "borrowed" from the 2nd stage and tone control
section of the Gibson GA-77 Vanguard from 1954.
If you compare them closely you'll find that the two circuits are completely
identical. Every component value & position, the 12AX7 valve configuration
and biasing, the tone network, and particularly - the grounding error on the
Bass Potentiometer.
