Stereo widener moves guitar from Center to Right (from 0-10) and gives a higher input signal up to a 4db increase.
Phase and Delay wideners moves guitar to the Left part of the stereo field (from 0-10) and about a 2db increase in signal.
Should these effects give a more balanced L -R signal? Is this the way those effects work?
It sounds like all they are doing is "panning" the guitar Left or Right but not actually spreading the guitar on both sides of the field.
