The BEST Parallel Effects Blender! GFI System Duophony | Secret Weapons Demo & Review

Confession: Ive been secretly using the Duophony on this page for over a month now. It's become the essential core of my Digital Amp rig, allowing me to blend between the UA Ruby and Dream without compromising on the stereo image of either. But with presets, MIDI, flexible routing, and an LFO (yeah), it'll do so much more.
