According to the schematics the boost of tone controls is done via grounding the negative feedback lines.but turn Bass and treble to full and push the loadness button (ON) the sound not boost .
Loudness switch is grounding the same lines - via resistors.
Once these lines are shorted to ground by tone controls then additional grounding via loudness switch has no effect - the lines are already fully grounded.
