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.
Comprehensive external control
• Expression Pedal - with adjustable heel and toe values.
• Aux Switches - accepts up to 3 external switches for versatile control (tap-tempo, bank up/down, etc).

Cheap and worth it.
Size: 42W x 28L, Color: Black
Cheap and looks nice, tbh.
I orders a 42wx28l and it was a nice fit.
I order 28L so the seam usually can sit above my ankle or shoe but It was a bit longer compared to my other various pants at 28L, it felt more like a 30L.
I’ve noticed the waist seems to fit a bit larger than I’m used to but overall a nice fit and material.
One thing worth mentioning is the stitching at the bottom seems a bit loose.

High Quality Cotton, Well Cut
Size: 36W x 32L, Color: Black
I was pretty impressed with the high quality of these pants. Remove the Amazon label and you wouldn't think twice if it had a Gap, Banana Repblic or Levi's instead. They are well cut and well stitched. I ordered black and the color looks great too. Fits to size.

Great fit
Size: 36W x 32L, Color: Dark Khaki
My boys love these pants. College son prefers them when he is golfing. They fit well and are comfortable. He usually wears southern tide brand which are extremely pricey. So happy to have found these. Already ordered in multiple colors. They are nice and thin for Florida weather

Great Pants
Size: 31W x 28L, Color: Black
I wasn’t sure what to expect when I ordered these, but I’m really glad I did. The pants look even better in person than in the photos , the color is accurate and the fabric has a nice, quality feel to it. The fit is spot on.
I bought it in 3-4 colors.

Decent for the price, but inconsistent quality
Size: 33W x 29L, Color: Dark Grey
Quality can be hit or miss. I ordered several pairs of the same "model" and fit is inconsistent. One pair fit great, another pair of a different color felt 3 sizes too small. Leg width can be slightly different from pant to pant or the legs have a bit of a "twist" sewn in them.
For the price, I'm not expecting perfection.
