I drew up the 2nd old schematic layout with the changes.



Then I took a shot at the new schematic but with no standing resistors.



I was also able to find a '81 Ibanez catalog that shows the frequencies for standard and bass guitar (new).

             Standard          Bass
Bass     230Hz              88Hz
Mid       600Hz             500Hz
Treble     2kHz            1.4kHz
