+==Phase Inversion: Unknown==
 This is a rather unusual schematic. Instead of putting the correct symbol in the schematic for the modulation ICs, they've just drawn actual ICs. We also can't tell the electrical polarity of the ICs that are opamps because "2" and "3", and "6" and "5" are not indicative. We'll have to go looking for the opamps to better understand. To the best of our knowledge, most, but not all opamps have negative on pins 2 and 6, and positive on 3, and 5, but not always. As with other pedals, we'll have to put this on an oscilloscope to make sure whether it inverts phase or not.

-On the schematic there are additional opamps and transistors, but they're dealing with modulation and power, not with sound, and so do not directly affect the signal in the pedal.
+On the schematic there are additional opamps and transistors shown, but they're controlling the modulation and power of the oscillator IC (seen very center).  Those remaining transistors and opamps aren't touching the sound signal directly, and so do not affect the signal phase in the pedal.
