I can't find a clear schematic for this thing anywhere. Bass, mid, treble, and pres is not responding. All resistors and electrolytics check out. Stumped so far. I think it may have a bad pot. Ideas?

The controls bleed frequency to ground. could find that exact schematic and the 1200 is blurry. but it looks like one of the tone pots goes to ground. I suspect it is not grounded
