The Lehle Dual SGoS pedal routes the signal via gold-plated relays to outputs A, B or T. Outputs A and B can feed two different amps simultaneously since the signal paths are electrically isolated by the Lehle LTHZ high-end transformer — completely eliminating humming loops. In this case, the potentiometers enable you to lower the output signal for A and B separately. Output T can be used for a tuner or a third amplifier. Both inputs can be routed in stereo to Outputs A and B. In addition, the Lehle Dual SGoS also incorporates gold-plated phase-reverse and ground switches. The Lehle Dual SGoS pedal can be controlled and synchronized with other Lehle SGoS Switchers via MIDI.
