GCX loops use no active circuitry, only the finest gold contact relays sealed in pure nitrogen. This gives the best possible reliability and tone. And GCX loops will add true bypass to any pedal effect to greatly improve tone when the effect is not being used.

Also included are two front-to-back feedthroughs, one with a very transparent, inline buffer. This buffer allows splitting to multiple amps and preamps, as well as reducing noise and loss of high frequencies from cabling. The GCX provides phantom power to the Ground Control over a standard 5-pin MIDI cable.
