The KOR KO-1 Chorus/Flanger Pedal from Aalberg Audio is a high-quality stereo in/out combined chorus and flanger stompbox that can be controlled wirelessly with the optional AERO AE-1 controller. The pedal offers different mono and stereo configurations including a dry/wet split and stereo panning from left to right, giving a more spacious feel to the flanger or chorus effect.
The KOR Chorus/Flanger can also be controlled by a free iOS/Android remote app that provides easy editing and allows the saving of presets for later recall. All the electronics are contained in a rugged, custom-made aluminum housing, while the onboard purple LED bars at the top provide actual parameter settings, easily seen from a distance or in low light. The KOR is powered by an optional 9V adapter.

- Controls
-
- Speed: Adjust the speed of the chorus/flanger effect
- Intensity: Adjust the dry/wet mix between the input signal and the effect signal. In Flanger mode, this parameter also adjusts the feedback amount
- Depth: Adjust the degree of pitch shifting in the chorus/flanger effect; Depth set to minimum means no effect
- FX-Select/ Flanger
- FX-Select: Choose active effect parameter (Speed, Intensity, or Depth) for wireless control (optional)
- Flanger: Press and hold the FX-Select footswitch to toggle between the two modes
- FLANGER (no light): Chorus mode active
- FLANGER (light): Flanger mode active
- On/Off: Set the pedal to ON (activated) or OFF (true bypass)
- Input/Output Setups
-
- Mono In/Mono Out: Connect your instrument to Mono In and the amplifier to Mono Out
- Mono to Stereo Spread: Connect your instrument to Mono In, then connect one amplifier to Mono Out, and another amplifier to Stereo Out. The stereo spread effect is a combination of phase inversion and a continuous panning of the signal from side to side, resulting in a wide stereo effect
- Dry/Wet Split: Connecting your instrument to Stereo In will split the dry wet signal as follows
- Mono Out: 100% wet signal
- Stereo Out: 100% dry signal
- Stereo to Stereo Spread: By plugging into both the mono and stereo inputs, and both mono and stereo outputs, you will obtain the same stereo spread effect achieved with the Mono to Stereo Spread connections. This is useful if you want to maintain the stereo image from the output of another pedal in your signal chain

Everything is great with this mouse. It is comfortable, responsive, and easy to use. The wireless connection works perfectly, and the battery lasts a long time. Very good value for the price, I highly recommend it.

Recommended for sure ts peak
Color: Matte Black
Not really the best at explaining, but here's something simple :v
This mouse works very well for everything in my opinion, especially gaming. It does has silent clicks, but as a GD player I click the mouse kinda hard, and it's a bit louder but that's ONLY because of the way I click. The mouse is very responsive and pretty comfortable, although I have no Idea what a 10/10 comfortable mouse feels like. This mouse is durable, don't ask how it happened, but it's survived a few drops and still works perfectly. As far as connectivity and compatibility, I'm not exactly sure, but it connected to my Windows 11 as soon as I plugged the driver in, it also connected to my PS5 without issues. To easily tell the size, it's about as wide as an apple, and as long as maybe half of a normal-sized water bottle. The 3 bars of lighting that show the battery percentage aren't exactly the brightest, but it's easy to tell that the mouse is on and how much battery it has. The easily accessible customizable DPI button has about 4 levels to choose from, which all work well, level 1 is pretty slow and level 4 is fast if you're unfamiliar with higher DPI. The 3rd setting for the DPI is very easy to control, I feel like it follows my movements at a very nice speed.

Nice yellow mouse
Color: matte yellow
The mouse is really nice, comfortable, and easy to use. It stands out on my computer desk thanks to its yellow color. It is wireless and charges via USB—it doesn't use batteries, which I’ve found to be excellent so far. I haven't been using it for very long, so I don't know how long the charge lasts.

A reliable mouse for people who don't need all the bells and whistles.
Color: Matte Black
I wanted a mouse without all the bells and whistles. I don't care about programming my mouse or having 18 ways to move it remotely. All I want is an ergonomic point and click device. This mouse meets my requirements. I give it four stars because, on waking my computer, the cursor is "frozen" until I click it. And, the mouse is a bit small for my hand. These nits aside, this mouse is perfect for my needs.

Reliable mouse.
Color: Matte Black
Amazing mouse if you want something simple for work, has good click sounds, doesn't need to be charged often, and is easy to transport! It also is really good for smoothness and comforting on grip.
