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.

You should change cabin air filter by yourself.
Do not let your dealership overcharge you for the work they did not perform. Use this to change cabinets air filter yourself. I noticed that my old cabin air filter was used both sides when I pulled it out to install this one. Not cool. I think this cabin air filter works as expected and air quality is definitely improved shortly after installation.

Good quality and price
Cheaper than autozone, and it arrives to my front door. Very easy to install, since I am not familiar doing very many things to my car, but youtube showed me, and 2 minutes later, it was done.
