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

I’m buying more!
Size: Twin, Color: White
The quality of this product is amazing! It looks fantastic, super fluffy and comfortable, keeps accidents from getting onto mattress. It works so well! And is so worth the cost, I’m buying more for the rest of the beds in our house.

Fits great and very comfortable
Size: Queen, Color: White
I purchased because my cat is older and I need something waterproof. It fit my queen bed and my deeper mattress that usually needs extra deep mattresses. It looks nice and went on the bed easily. I have not had her test its waterproof feather yet. I am relieved I do not need to worry or put pee pads down for her.
I reas some people find it hot and hear a squeaky sound. I have not experienced either. The padding is a nice addition. I was surprised by the soft padding feature as I was not looking for it. The price was great. I did not want to spend a lot of money for something that did not need forever given my cat is older with kidney problems now. I will not remove it even if it is not needed anymore because I like the cushion.
I have purchased the Bedsure brand for other items and always been pleased with their price and quality. I recommend this product

Perfect to stop leaks or stains
Size: Twin, Color: White
This is a wonderful mattress protector that gets the job done. It absolutely prevents stains from leaking through to the mattress. The only thing I don’t like that could be improved is the size and lack of snug fit. It moves a lot but still does the job and is not too hot. It’s very soft and comfortable. Would be 5 star if it had a snug feature or bands to fit under the mattress. Worth it for the price and is long lasting.
