GFI System Duophony Advanced Parallel Signal Blender PedalAbout the Product
Parallel Blender: A pedal that blends the signals from 2 or more sources.
Duophony is their take on the lowly 'parallel blender' pedal. They took the basic concept of blending two effects together to the next level by integrating the classic signal blender functionalities with modern features and intuitive user interface. The result is a solid blending machine, optimized to help you unleash the unexplored ideas of parallel blending and discover new ways of sculpting limitless soundscape!
Full stereo signal paths
Duophony features full stereo signal paths throughout. TRS jacks supports both mono and stereo connections for the inputs and effect loops, while dedicated Left and Right TS jacks are provided for the outputs.
Hassle-free blending with presets
16 presets, readily accessible via the two on-board footswitches, external aux-switches, and MIDI.
Expressive Flexibility
Adjust blending ratio or the Dry signal level at will with an expression pedal!
Fully configurable Heel and Toe values for flexible expressive control. Expression pedals with 10 KOhm pot value are supported.
Modulated Blending
A unique feature that Duophony has is “Modulated Blending”, the ability to modulate the blending action with an internal LFO. When modulation is activated, an internal LFO will produce a waveform whose shape maps directly to the blend ratio. Modulation speed can be controlled via expression pedal, tap-tempo, or MIDI clock.

Love the moisturizer, hate the smell
Style: Jar
I received a sample of this in an ipsy box and loved it. I have combination/dry skin, and this is so moisturizing. It also works well under makeup. The smell is terrible though--reminds me of am old perfume, and it's hard for me to ignore. I would absolutely rate this 5 stars if they got rid of the fragrance.
