Featuring eight true bypass audio loops, two front-to-back feedthroughs, and options for buffered or passive inputs, the Voodoo Lab GCX Audio Switcher is an elegant solution to any audio routing conundrum. Built with gold relays sealed in nitrogen and no active circuitry in the bypass loops, the GCX delivers pure, unfiltered audio signal routing as well as A/B routing for easy toggling between amps and preamps. Perfectly paired with the Voodoo Lab Ground Control for total channel mastery, this is the perfect option for guitarists with massive rigs who need to quickly rifle through their options.
