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.

great mouse
Color: Black and Gold
really good mouse, the sound isn’t loud, i love the little scroller and ive used it daily for a few months now and the batteries life has lasted since then and i haven’t had to change them out which is great. it’s very lightweight and it will go into i think maybe a resting mode after not using it for a few minutes and you have to click to turn it back on which i do like. it fits very nicely in my hand and it’s overall a great mouse.

Quite clicks and easy manueverability. Works great.
Color: White and Gold
I was very pleased when I opened the box and seen that the actual mouse looks exactly like the pictures. It is lightweight and glides easily along my mouse pad. The colors are gorgeous and makes it look very chic! And it works great. It was easy to set up, just plugged in the USB receiver and it was up and running right away. The clicks make a muffled sound that is kind of soothing.

I hold this more than my husband's hand!
Color: Black and Gold
So much about this mouse is RIGHT!! The smooth feel in my hand, the way it glides across the mouse pad, and the silent scrolling and clicking feature are all great features I look for in a mouse. As an online college student, homeschooling mother, writer, digital designer, and business owner, a computer mouse is one of my most used "tools".
The battery life seems to be alright, although I did not realize it was ran on batteries and am not looking forward to the ongoing replenishment of that. I would prefer a mouse that charges if it were to be wireless or just have that cord attached. It responds with my computer and laptop well with little to no lag.
Visually, it is gorgeous, classy and professional while also being cute! The black with the rose gold colors really make a statement.
Aside from the longevity and sustainability of batteries, I love everything about this mouse. Show me this mouse with a few upgrades and the ability to charge an internal battery and I will be all over that with 5 stars!

Quiet, Sleek, and Surprisingly Premium for the Price
Color: White and Gold
I’ve gone through a lot of wireless mice over the years, but this one genuinely surprised me. The design looks much more premium in person — the black and gold finish gives it a sleek modern setup vibe without looking cheap or flashy.
The mouse is super lightweight, smooth, and almost silent when clicking, which honestly makes a bigger difference than I expected. Great for late-night work, studying, or coffee shop use without annoying everyone around you.
Setup took seconds — plugged in the nano receiver and it worked instantly with my laptop. No lag, no connection issues, and the tracking has been very responsive on different surfaces. Battery life has also been solid so far.
For the price, this feels like one of those underrated tech finds that ends up becoming part of your everyday setup. Clean aesthetic, quiet performance, portable, and reliable. Definitely exceeded expectations.
