Lehle Dual SGoS – Precision Amp Switching with MIDI Control. The Lehle Dual SGoS is a high-end ABY switcher designed for guitarists and bassists seeking ultimate control over dual-amp setups. Whether you're running two amps individually, simultaneously, or adding a third output for creative routing, the Dual SGoS delivers silent, hum-free switching with studio-grade clarity! Outputs A and B are electrically isolated using Lehle’s custom LTHZ transformers, eliminating ground loop hum while preserving your tone. Each output includes a dedicated level control—perfect for balancing amp volumes when running both in stereo. A third output (T) is available for connecting a tuner, a third amp, or even an extra channel. The Dual SGoS also offers MIDI integration, allowing you to program amp switching and recall settings in sync with your MIDI rig. You can use it on its own or combine it with other Lehle SGoS devices for more advanced switching configurations. Built with gold-plated relays, soft-touch switching, and Lehle’s renowned engineering, the Dual SGoS is your solution for reliable, transparent, and flexible amp control—on stage or in the studio!
