Wellllll, all wired up. On the new jack, you have to test with an ohm meter. Both short lugs are the same size, one is hot, other ground, long lug not in use. Only problem is that if you wire your pots per the schematic, align them as shown, and wire them as shown, all volume and tones are backwards. Clockwise to decrease volume. Guess I should have checked them with a meter prior. When I get done, I will try to draw a new schematic with correct orientation (as your looking at the back of the bass) for a 4 wire Humbucker. Hope to finish up this week.
