Line 6's Relay G10SII Guitar Wireless System is as powerful as it is compact. This stompbox-sized pedal offers professional features, rugged build quality, and plug-and-play operation at an easily affordable price. The Relay G10SII system integrates seamlessly into any pedalboard or can function as a standalone unit. It features an impressive range of up to 130ft line-of-sight, enabling you to move about untethered on any sized stage - and the Relay G10SII works equally well with bass.
