What makes the chorus and vibrato effects stereo? (other than the obvious, that they have two channels!) Are the left and right channels out of phase when using the chorus effect? If so, how many degrees out of phase? Do both channels change pitch in unison when using the vibrato effect or does the effect use the two channels in a different way somehow? I understand the way the effects are implemented might vary greatly between the different versions of the amp.
