The ST-MIX is an accessory pedal that integrates the Memory Lane delay and other stereo effect pedals into a multi-amp stereo sound field setup. A special PAN IN input allows the user to place the output of an effect anywhere between two amplifiers ? this makes it possible for example to run a stereo chorus wide out to two amps while placing a mono delay output in between the two amps. Multiple output path options including a straight-through bypass for the left channel allow optimization for particular multi-amp setups, with integral transformer isolation for the right channel to mitigate ground loop hum. A phase footswitch allows on the fly in-phase / out-of-phase switching of the left-right output channels.
