Wrong I'm afraid, I wish it were that simple. To fix it you'll either need a new blender pedal (like the Xotic X-Blender or Wounded Paw) that has a phase invert switch, or stick another pedal in the loop just before or after the Bassballs that also inverts the phase. Many simple boost pedals invert the phase, e.g. my Cream Pie, Phat Phuk, and even SFT do.
