Anyone know of a DIY circuit for just a feedback loop? Would be ideal for when I can't have my amp as loud as I would like at home and at some gigs. Just a momentary switch with some kind of feedback loop would be great, but I do not know how to make a feedback loop  |

IDK of a DIY circuit but I have seen one posted before.
Also Ernie Earplugs seems to sell alot of them on E-Bay...
Is that the same Aron that runs the other forum ?

Yeah that may be it,or at least pretty close to the one I saw.
I think thats all the other one I saw for sale is.
I did something like that with my BMP,A phase switch might be good for this type of thing.
So you can change on the fly.

Cheers for the suggestion but I don't want a loop pedal with a feedback control, I just want a feedback pedal, so I press the button and what ever note I am playing turns into feedback?

So when you say feedback, do you mean like when a guitar is too close to a loud amp? Or are you talking about feedbing back the output signal into the input? |

Guitar to close to a loud amp I think Boss have a distortion/feedbacker pedal or something? That's a very difficult thing to make sound convincing. The Boss one is in the ballpark, but it's a horrendously complex circuit. You might look at the "transduce anything" thread at diystompboxes.com, there are some alternative techniques (i.e. thinking outside the stompbox) described there. |

It's the DF-2 Super Feedbacker and Distortion. My neighbor has one, and to me it sounds more like a sample-and-hold type of effect that eventually oscillates into high-pitch feedback. It's very odd. And yes, as Alex points out, it's hella-complex. I opened it up and the PCB is jammed full of components. It's quite impressive, actually. |

How about a good ol' fashioned booster?
Just make it louder until it feeds back.

Fair enough, in my 'noobyness' I thought it would be a relatively simple circuit, how wrong I was haha!

I can borrow my neighbor's pedal and take some gut shots. Maybe analogguru at FSB will be able to tell something from having a look. Or, more likely, he already has the schematic.  |

Cool cheers, I'll check it out though I guess the schematic will be too complex for me to read and understand. The simple EHX LPB took me a good few hours to wrap my head around it Good sense of achievement when I finally did though. What about a self-oscillation switch like on delay pedals such as the Solid Gold FX Electroman? http://www.youtube.com/watch?v=Bm0a9Zwn7p8Is that achieved by feeding some of the output back through the circuit?? |

Self oscillation in a delay is something I don't 100% understand. But it happens when you have the repeats high and the wet/dry mix on the wetter side. Basically the repeats start going on forever and degrade every time they are reproduced.
