How can I operate the pedal stereo?

A stereo jack cable or a so-called “TRS” cable must be used for the signal input and output. This has a stereo jack (male) and two jack sockets (female) which are split into the left and right signals. If a stereo signal is present at the input, the selector switch on the front of the pedal must be set to stereo. If only a mono signal is present (e.g. the direct guitar signal), the switch should be set to mono.
