Get more control over your guitar effects with the Digital Music GCX Guitar Audio Switcher. Use each of the 8 loops for in/out effect switching, A/B switching to select amps and preamps, or to control any type of footswitch function such as amp channel switching. Add a mixer to create a parallel effects system and use GCX loops to mute the inputs to your rack effects. This allows effects like delay and reverb to trail off naturally. GCX loops use no active circuitry, only the finest gold contact-relays sealed in pure nitrogen. Add true bypass to any pedal effect to greatly improve tone when the effect is not being used. 2 front-to-back feedthroughs, one with a very transparent, inline buffer. Buffer allows splitting to multiple amps and preamps, also reduces noise and loss of high frequencies from cabling. Provides phantom power to the Digital Music Ground Control over a standard 5-pin MIDI cable.
