USINg ThE POLARITY REVERSE SWITCh
Some pedals will reverse the relative phase of the signal. This is normal as pedals are usually in series with each other and
changing the phase has no audible effect. When activating the effects loop on the Mix-Blender, you are actually creating a
parallel signal chain whereby the dry and wet signals are combined. If the wet and dry signal are out of phase with each other,
you will experience phase cancellation.
Set the BLEND control to 12 o’clock. If you notice that the sound gets thin or disappears, this means the pedals are reversing
the relative phase and the signal is being cancelled out. Simply push the 180º degree polarity reverse switch to the up position
to compensate.
