The GFI System Duophony Signal Blender is a dual parallel processing pedal with an LFO for modulating between the two different signal chains.
I can be either stereo in/out or mono and can mix the two FX Loop channels normally (just like a regular mixer) or use the built-in LFO to modulate between the two, which can create interesting and creative textures.
The settings can be saved to presets, allowing you to easily switch between different speeds and waveshapes.
Whether you want more control over your signal chain, need direct access to two different setups, or want to integrate multiple instruments experimentally, the GFI Duophony can be an extremely useful utility device.
