The GigRig PLUS4 Sometimes you simply need more loops. Whether your switching system is already full, or you just want to add more pedals to your rig, PLUS4 gives you a simple and completely transparent way to add, and remotely switch up to four additional effects loops. Designed to integrate seamlessly with G3S and G3S Atom, PLUS4 expands your switching system while keeping your signal path completely pristine. With two independent signal paths, PLUS4 can be configured as four mono effects loops in series or two stereo loops, giving you the flexibility to switch anything from classic stompboxes to modern stereo pedals. And because the loops are fully passive and relay switched with ZERO filtering, you can confidently use it with any pedal, including impedance-sensitive designs like germanium fuzzes and vintage treble boosters right up to modern day instrument and line level effects.
