Description
Long guitar cable runs usually mean tone loss, hum, or a compromised signal chain — the Radial SGI solves that problem by converting your guitar signal into a balanced, transformer-isolated feed that travels cleanly over standard mic cable for up to 100 meters (328 feet). It’s built as a two-piece system: the SGI-TX transmit module and the SGI-RX receive module, letting players stay in the control room (or off in the wings on a big stage) while the amp and cab live wherever the sound actually needs to happen.
- Drives a guitar signal up to 300 feet with no signal loss
- SGI-TX runs 100% discreet Class-A circuitry for a natural, uncompromised tone
- Drag Control on the TX lets you dial in correct pickup loading for your specific guitar
- Opposing isolation transformers in both modules cancel ground-loop hum and buzz
- Passive SGI-RX pairs with a ground lift switch for extra noise control
- Connects with standard 1/4″ instrument cable and balanced XLR mic cable — no proprietary wiring
- Plug-and-play setup, includes power supply
On stage, this makes it easy to route a guitar signal from a wireless receiver back to a pedalboard and amp without hauling extra gear or fighting interference. In the studio, it means the player can perform in a comfortable room while the amp mics up separately, with zero degradation between the two. Either way, the SGI keeps the guitar’s character intact across long distances — exactly what a rider-friendly, scalable rig needs.
