Title: Live feedback
Post by: Kollaps on February 22, 2015, 05:14:09 AM

Hey,

I'm working on a couple of ideas with feedback (you can hear on the soundcloud demo below). I made it very simply by running mic through the distortion on a SP404sx and holding it up to computer speakers. Simple.

I want to do get this kind of distortion during live performances. I have an old 76' Fender Twin Reverb that I use for guitar playing + feedback but I can't get the type of controlled feedback through it like I am getting in the demo - only ear shredding, super high frequencies that I feel are unusable.

Any suggestions on how to get this live-friendly?

Cheers.

Why not record it to sampler or dub it to tape/CD/mp3 player to mix in with the rest of your live performance?

or you could bring your small speakers as part of your live set up, and run an aux send (or headphones out) into them with your mic/distortion on its own channel.

This is what I recommend. It is very different kind of feedback one gets from small speakers and amplifiers.
I have seen for example mr. Tommi Keränen perform live, that he has all those usual shakers, contact mics and turntable arms etc on table, BUT also small speakers elements. Not even in box, just the small speaker element on table. Size slightly bigger than contact microphone. By placing that usual home made piezzo contact mic on top of speaker element, it would result utterly piercing feedback. It shreds on PA system, but on table, where it actually happens, it's easy to control. With normal dynamic microphone, I'm sure controlling pitch/tone etc is more advanced than with limited range of piezzo...

And, if you don't have any small speakers etc, I'm pretty sure there is headphones. Right ones can work just fine to have similar results.

I don't think you need to mic those small speakers to get sound such as you linked.
Such sound would be easier done if the feedback happens from microphone into mixer - headphones output speaker back to microphone. And sound to PA goes from mixer main output.

headphones output [to] speaker
Aux send/FX send output would make more sense since them you can put just the microphone thru your feedback-speaker (assuming it's a small cheap mixer where you can't send specific things to the monitor/headphones that is)

That is of course better, but I have had mixers without any aux/effect send channels. But usually these functions are in cheap and small mixers too.

I use a small mixer for live with control room outputs. Could I hook up monitor speaker that are on stage and use them for more feedback?

Indeed you could. Dunno what all you guys are doing to have trouble feeding back live tho, I can feed back at headphone volumes levels :D

(But yeah some little amp from any convenient send/headphone/monitor out on your mixer would work fine as an extra monitor and feedback speaker)

it's not really a problem, more of an inconvenience that mics don't feedback the same than in the recording environment. Probably cause of the distance of the live pa system
