Silent Switching. Absolute Control. The Lehle 1AT3 SGoS is a professional-grade switching solution that lets you route one instrument to up to three separate outputs. Whether you’re running multiple amps, integrating effects loops, or managing complex stage rigs, the 1AT3 delivers precision control with zero compromise. Built for Complex Rigs With one input and three individually switchable outputs, the 1AT3 makes it easy to toggle between amps, engage or bypass entire signal chains, or send your signal to a dedicated tuner output. The unique C to B routing option allows Output C to function as an effects loop for Output B. This makes it possible to include or exclude a pedal chain instantly. It is a powerful feature for wet and dry setups, multi-amp rigs, or programmable touring systems. No Pops. No Hum. No Tone Loss. At the heart of the 1AT3 are Lehle’s gold-contact relays, designed for ultra-quiet switching with no mechanical wear. These relays switch both the signal and ground simultaneously, significantly reducing the risk of ground loops when using multiple amplifiers. Your signal remains clear, dynamic, and completely intact from input to output. Programmable and MIDI-Ready Like other SGoS units, the 1AT3 can operate as a standalone switcher or integrate seamlessly into a MIDI-controlled setup. This makes it ideal for modern touring rigs that demand precision and repeatability at the press of a button.
