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

Great product! Durable, chewable, awesomeness!
Color: Grilled color, Color: Grilled color
Very well made and durable. My dog hasn't left them alone since i opened them. Hes been at it for about 45 minutes straight now! Lol. He's an avid chewer. He will chew thru and fabric or cloth toys in less then a day. But these are what he really likes because they take time to chew apart. The shapes, are great, because one he props up with his paws and chews and it seems like it's easy to grip for him. Thru are hard so if you have hard floors it can get a bit noisy when he drops them. Over all this is a great product. Safe, chewable, long lasting, fun shape looks real to him (i think lol), Me and my dog Lucky are both happy with his new toys!

Amazingly great product!
Color: Grilled color
I’m not just saying this, ok, this is not hyperbole: this is THE best nylon bone for chewing that I have ever purchased. And you get TWO of them for relatively less expensive than most chew toys give you one! I have 2 golden retrievers, and if you know goldens, you know that they are some of the most relentless and powerful chewers around. So I can’t give them almost any toy other than rubber stuff or it will be destroyed in a period of time that doesn’t make it worth it. One of them even figured out how to destroy a supposedly indestructible toy made out of kevlar! She was able to get into it through the seam, which is not kevlar ha ha. Anyway, I digress; I never even considered nylon chews because they suck! Usually. Usually my dogs in the past have lost interest with them in less than a day. I took a chance on these mainly because of the novel shapes, the fact that they give you two, and the low price. Both my goldens LOVE these! Not just for one day, but going on weeks now! I don’t know if it’s the flavor or what, but I will see them gnawing on one of them at some point every day. And they CAN’T destroy them (I knew nylon was good for that, but it was the “who cares” attitude of my previous dogs toward nylon that kept me away). Both the “ribs” and “steak” (quite clever) are a bit worn on the edges now, but they look like they will be around for years. You can’t go wrong with this product (unless for some reason your dog does not like the flavor, but the flavor seems to be what draws my dogs to them). I highly recommend this (these) as the most cost-effective chew toy I’ve ever purchased.

Great for larger dogs
Color: Grilled color
I think they were heavy duty and durable, but they were too heavy for my dog. The seller was excellent though!
