Definitely not stock. I'd like to see the whole setup to figure out just what's going on.
Those odd little things are trimpots, which can be used to fine tune resistance. The orange thing is a capacitor, 2.2nf, which is a common value on treble bleed circuits. I can't tell what all connects to what, but my first guess is a previous owner used the trim pots to find the sweet spot for the treble bleed.
