Using the polarity reverse
If you notice that the signal becomes weak when you blend the wet
with the dry signals using the MIX control, one of your pedals is likely
reversing the polarity which in turn is causing phase cancellation when
mixed with the original dry signal.

CANCELLATION
This is common with guitar effect pedals as manufacturers rarely pay
attention to absolute phase. If the sound is weak because an effect pedal
is inverting it’s output, compensate by pushing in the recessed 180°
polarity reverse. This will invert the wet signal and bring it into phase with
the dry signal to create a full sound.
