* Prices may vary. Check retailer for current pricing and availability.
The Lehle Dual SGoS is a serious piece of kit for gigging musicians who need clean, reliable amp switching. The transformer-buffered design is a game-changer for eliminating ground hum, and the independent attenuation is a real time-saver. It’s a bit of a splurge, but if you’re tired of wrestling with cables and noisy rigs, this is a worthwhile upgrade.
Product Description
- Lehle Dual SGoS
- Switcher
- For two amps plus tuner with high impedance LTHZ transformer and gain reduction
- The Lehle Dual switches the signal via gold-plated relays to outputs A
- B or T
- Outputs A and B can be operated at the same time on two different amps
- since A to B is galvanically isolated by the high-end transformer Lehle LTHZ - ground loops are thereby excluded
- With the potentiometers
- the outputs A and B can be attenuated separately
- The output T is available for a tuner or a third amp
- The two inputs can be stereo-routed to outputs A and B.
- In addition
- the Lehle Dual has a gold-plated phase reversal and a ground switch
- The Lehle Dual can be controlled via MIDI and networked with other Lehle SGoS switches
- Power supply available as an option
PROS
- • Gold-plated relays ensure pristine, reliable signal switching.
- • LTHZ transformer eliminates ground loops, a huge benefit for live rigs.
- • Independent attenuation on channels A and B allows precise volume balancing.
- • Stereo routing capability adds flexibility for creative signal paths.
CONS
- • Premium-priced, a significant investment for a switcher.
- • Relay-based switching can introduce a tiny bit of latency – negligible for most.
- • Size and weight make it less ideal for extremely compact pedalboards.
