Is there any guitar amp feedback simulation effect out there? I've been looking and I havent found one. It would also be great to get that 60s echo-feedback effect. Am I dreaming here?

Predatohm is the answer to your prayers.It's got some fairly natural feedback stuff happening if you play around with it.
Comb filters can do nice feedbacky effects as well.

Slayer 2 does some good feedback.

There's a very good free one being developed at Betabugs Audio but it's either Alpha or Beta bench testing right now. You could go to betabugsaudio.com on their site forum and ask Mully if you could try it. I made a little track with it right away after I got hold of it and was very happy with what I got.

It's called Feedbug.

Interesting bugs!

Anyone (Mully?) know what the status of FeedBug is? The last mention of it in the BetaBugs forum is sometime late last year.

I fed a guitar into the FX version of Slayer 2, but really didn't get any feedback that sounded like the feedback you get with the internal slayer sounds. Anyone else have luck getting feedback from the FX version of Slayer?

feedbug is still in development.... it's a superb plug but not quite there yet..... it will kick some serious ass once it is done

Quick response, Mully! Thanks - can't wait!

but like Brad said.... if you join the betabugs forum and drop me a pm you "might" get access to the betatest area... where the latest beta is flying around....

I love feedback assisted sustain, but I don't believe it's possible to achieve this realistically with an effect or plugin. Boss had a distortion pedal years ago that had a "feedback" button - but it was just a wimpy little oscillator that sounded dorky. The real thing is a physical action that vibrates the string, very similar to an ebow. The best news, however, is that you don't need large amps and speaker to make this happen. I get the best controllable feeback with a 9 volt Fender battery amp. It might look like a toy, but it squeals better than a Marshal stack - and at very low volume, that would never be a problem with neigbours! If you like using VST amp sims, try this: get a signal splitter (some tuners have two outputs) and feed a battery amp and your soundcard at the same time. You are recording just the dry sound from the guitar, so the amp has nothing to do with the tone you get. But the feed back is physically vibrating your string, so you get the real feedback in your sound - magic.

magic

wow

The thing about real feedback sustain is that you can literally have infinite sustain, because the sympathetic vibration from the speaker keeps the string vibrating forever. Plus, you can vibrato or whammy your string - that is something a VST effect could never do realistically. Plus, you can let the feedback get out of control, by pointing your strings at the speaker, for really crazy effects. Another trick used by some of the big hair metal gods to get the exact note of feedback at the right time: the small amp that you use for feedback can be severely eq boosted to make it feedback on the exact note you want. I guess using VST, you could route your signal through a filter with resonance, or a parametric eq, and then back to the battery amp. You could even have specific eq curves for different notes - automatable now with VST. Obviously this has to been done while tracking the part ... but could be a lot of fun ... imagine recording a lead break knowing that at the exact moment you need a specific feedback note the filter will change to ensure you nail it ...

It is unclear if the original poster plays a real guitar but if he does feedback can be achieved fairly easy the old fasion way.
Just bring the guitar pickup close to your monitors.
You don't need high volumes to do this.

greendoor · Post by **greendoor** » Wed Apr 27, 2005 5:28 am

I haven't had great success doing that. Little battery guitar amps have lots of gain and the peaky response that induces feedback really easy. And yes, if you are playing virtual guitar you are screwed. Fly in some samples from somebody who has the real thing.

greendoor · Post by **greendoor** » Wed Apr 27, 2005 5:32 am

I guess a delay with a sharp filter could be induced to feedback on a specific note. Not as much fun as holding a wildy feedbacking guitar ...

Guitar amp feedback simulation?
