Search wasn't working, but what exactly does a feedback loop do? Can I create one with a normal loop pedal? I've played with them before and understand what they have the potential to do sonically, but what's actually going on is my question I guess?

It feeds the pedal output back to the input. If there is no volume/amount knob, usually the full amount of output goes back into the input of the pedal. The volume amound knob allows you to attenuate the the amount of output going to the input. Much like feedback from a guitar or feedback on a delay pedal.

So if you use a modulation pedal, you are remodulating the modulation potentially an infinite amount of times. With a distortion or fuzz, you are sending the gained/boosted/distorted signal perpetually back to another stage of gain/boost/distortion usually creating oscillation. This is why sometimes pedals that attenuate don't work that well.

You'd have to wire the output of the loop pedal back to the input. Something passive (without power) would be easiest. Something like the Boss (sorry, originally wrote Morely, but those are usually A/B switches) ones that require power would be more difficult. You could probably pull it off with one of those big swiching pedals and a stereo pedal. Much like making those old boss stereo in/out pedals and feeding one output back to the input to make it oscillate.

They are really simple to build.

Nice answer...

When you say normal loop pedlol are you saying a loop switching pedlol or a loop recording pedlol??? Cause depending on things, yes on both...

Good point, sonidero. I guess I just assumed BoatRich meant bypass loop pedals. I forgot about loopers.

edit: just thought about it: here is a simple way to do it too with a mixing board
Simple Feedback Loop: http://youtu.be/qk6NQvXSizg

A stereo looper set up correctly and always recording will act like a tape loop doing sound on sound... With some pedlols between out and in you could feedback it up fo sho...

If you have a compact mixer all you gotta do is hook up an output to an input and ta-da! This some pedals in there and yay! But keep your hands close to the master vol cause it can get crazy.

Always thought this was kind-of neat demo from MASF. I'm sure other's have done it before but this is just showing you a literal external demonstration of a feedback loop.

That's cool...

Here's the Master...

Dude, this inspired me to do this with my BigSky. The results were awesome! Especially in Shimmer mode, I got a crumbly bass sound out of it. I might try to make a noise album just using it.

This is really cool, I'm definitely going to try this with some of my stereo effects. Would it work with a tabletop unit like an Alesis Ineko?

Also, thanks for all of the information. I meant a bypass looper, but good to know that I can use my loop pedal to do this. If I'm reading correctly, I would just plug one out into an in and then loop a message right? Also, I'd seen that mixer video but didn't really understand it, and the explanation definitely made it make more sense.

Well now I have to try this

That's pretty darned cool. Really nice sounds. That takes some patience and skill.

I don't see why it wouldn't work with the Ineko as long as it has positive gain (even then it might). The guy in the video that sonidero posted was using rackmount effects and mixers. It's all the same idea. The fun of this stuff is experimenting; try anything you want. Get creative with the wiring and orders. Find out what works and doesn't.

That's one fancy noise oscillator there. Throw some other pedals in the chain before you feedback to the input...and clips! Starve some power supplies too.

I know, now I have to get a looper...(don't know why I don't have one anyway, but...).

I run two Ineko's in a feedback loop - some settings work better than others, but it's a great tool for feedback-scaping. Haven't built a loop using just the/an ineko, but no reason to think it wouldnt work especially on gain-ier presets.

But don't forget the first and second rule of feedbackloopclub - buy a graphic EQ! Not only will that give you positive gain, essentially if you're using other pedals that may have a drop in volume/output/gain, but it's an EQ! Use it to fuck with the frequency range of the loop in real time - grumble mumbles to squealing spikes.
