Essential Information About the Lehle 1at3 SGoS Switcher
- Programmable ABC Switching to control up to three amplifiers (or one amp, a tuner, an effects chain) with clear and fast routing.
- True Bypass via gold-contact relays, without semiconductors in the audio path, to preserve signal integrity and dynamics.
- Loop C to B: the C output, combined with the C to B jack, can serve as a dedicated effects loop for the amp on B to instantly exclude unused effects from the signal chain.
- Silent switching and ground loop prevention: active suppression of switching noises and switching of both signal and ground to avoid hum when changing between A, B, and C.

SGoS: Lehle's "Second Generation of Switching"
The Lehle 1at3 SGoS fits within the brand's philosophy: high-end routing designed for demanding pedalboards and multi-amp rigs where reliability is as important as sound quality. The SGoS series adds an advanced control layer with a simple programming approach, while retaining what defines Lehle's DNA: precise, fast switching built to last, with a robust footswitch mechanism and optimized control electronics to minimize unwanted noise.
For Which Musicians and Setups?
This switcher is ideal for guitarists and bassists who play live (clean transitions between multiple amps, chain changes, tuner management) as well as for the studio (amp comparison, re-amping, quick takes without repatching). It is especially suited for musicians who alternate between different amp tones (clean, crunch, high-gain) or who want a simple system to remove the tuner and certain effects from the audio path when not needed.
Rock, blues, pop, metal, indie, worship, session work: whenever your setup requires clear and repeatable changes, programming and remote control via MIDI Program Change become a real convenience. The pedal format naturally fits on a pedalboard, and the visibility of A, B, C states makes it easy to use on stage.

Questions frequently asked
Lehle 1at3 SGoS: how many amps can it handle?
Three 6.35 mm jack outputs A, B, and C allow routing the signal to three amps or destinations. Switching is done by gold contact relays with active suppression of pop and click noises.
Can an effects loop be integrated with output B?
The loop function uses output C and the C to B input to insert a series effects chain on the amp connected to B. A switch then allows toggling between the direct and processed signal.
Is the switcher controllable via MIDI?
The Remote jack (6.35 mm TRS) accepts control via MIDI Program Change messages and communication with other SGoS switchers. A stereo cable is sufficient for this connection.
What is the impact on guitar or bass sound?
The audio path is switched by relays without active components inserted in the signal. This design preserves the instrument's attack, dynamics, and response. Ground management during switching helps limit noise in multi-amp setups.
What power supply is needed for this Lehle switcher?
An external 8 to 20 V DC power supply is required, with a current consumption of 97 mA. The power supply is not included.
