This True Bypass pedal switches the signals from magnetic and piezo pick-ups just as free of losses and background noise as it does line signals. The secret is in its gold-plated-contact relays and its active pop-and-click suppression. Any differences in level can be ironed out, and Outputs A and B lowered relative to C.
You can also feed signals from totally different sound sources, such as keyboards and CD/MP3 players, to an amp or a PA channel. All inputs and outputs, plus the internal signal path, are stereo. Press the active footswitch again to route the signal to the second output, and thus to an instrument tuner, another amp, or a mixing console channel.
The Lehle 3at1 SGoS can be remote controlled using MIDI program change commands. You can also network the unit with other Lehle SGoS switchers via a stereo jack socket.
