What is a KRÖK?
This is a question that has plagued humankind since the dawn of time. Or at least since last week, when the KRÖK was invented. I'm told the KRÖK means "bend" in Swedish. Sounds about right.
But the KRÖK is actually an effects pedal. It has two functions:
- It's an effects loop. Effects loops are handy for a number of reasons: They can keep noisy pedals out of your signal chain; they allow you to turn on (or off) several effects at once; and they can essentially "add" an on/off stompswitch to effects that don't have one. Pretty fucking snazzy, huh?
- It's a feedback loop. This is the main and true and right reason for the existence of the KRÖK. A feedback loop takes the output of a pedal (or pedals) and sends it back to the input of that pedal (pedals), creating an unholy cacophony of noise. Put effects in the loop, turn the knobs, hit record, be amazed at the results. It's endless hours of fun!
The pedal is pretty simple, but if you need instructions, here goes.
Plug the KRÖK in your chain. Guitar goes in on the right side and out to amp on the left, like just about every other pedal in the known universe. Stuff in your effects/feedback loop is handled the same way: SEND goes to the IN of the first pedal in the loop chain, and RETURN goes to the OUT of the last pedal.
Got it? Good.
The stomp switch turns the loop on or off. When it's off, signal passes from your guitar/bass/synth/keytar/harmonium/whatever straight through the pedal untouched. When it's on, the LOOP is activated.
The fdbk toggle switch determines what the loop does. When it's toggled to the left (toward the "0"), the feedback loop is off, which means the KRÖK is acting as an effects loop. When the toggle is to the right (toward the "1"), the feedback loop is alive, and it'll take whatever comes out of the loop chain and send it back to the beginning, ad infinitum. Good times...
When the feedback loop is alive, the fdbk level knob controls the feedback level — sort of. You'll see what I mean when you start experimenting with the feedback loop. Feedback loops are unpredicable beasts, and you never know what they're gonna do. Especially if you have a time-based effect like a delay in the loop. So, yeah. The level knob may control the level, and it may not. Sue me.
One more interesting tidbit about controls: When you have a guitar or other instrument plugged in to the KRÖK, the volume knob on your guitar will control the feedback level. Why? I have no idea. It just does.
Another random warning: Re. the aforementioned unpredictability of feedback loops: Mind your speakers. Sometimes feedback loops will generate ungodly volume spikes for no apparent reason. So don't blow up your stuff. You've been warned.
