Anyone expercience in controlling feedback?

I know you can get feedback easily turning on you sustain pedal (or reverb). But does anybody know how to control these feedback.
The place/position of your guitar - amp does matter too... any theory about this one?

i think hes talking about minipulating feedback, not getting rid of it

Sorry, was'nt too clear about this one :P (probably my crappy English)
As User01 stated, I want to USE the feedback in (a) song(s), thus control it!
I don't wanna raise my hands and let the chaos begin .

I you strike a note and vibrate the string (with the amp loud enough!) your note tend to 'feedback' or sing a whole octave higher than the original one. Not that that easlily to obtain this note without unwanted noise. So i'm looking for some suggestions to obtain this 'feedback' more efficient.

I head some people say it even depends of your (with guitar off course) position in the room. But I can't find any background/theory about this one.

heres what i do...

turn around and face the amp

good feedback needs high volume, and the louder it is, the further you can stand from the amp

distortion helps a bit

and it will almost always take some time to set in and get loud

muting different strings can select which pitches come out of the amp

controlling it though... you can mess with the pitch if you have a whammy bar. Try feeding back and playing with the whammy (if you have one) and you can get some cool stuf... if you dont have a whammy, push the strings above the nut, that can give you a similar effect.

If you mute the strings, you can still get direct feedback (from amp --> pickup, instead of amp --> strings --> pickup), but you cant mess with it unless you have pedals... i'd think having a bunch of EQ pedals would do some cool stuff to it... but theres a chance that it would interrupt the wave and just cut if off alltogether.

try some of that... see where you get

facing the amp wil cause more feedback, but u probaly knew that already

yea
kerry king pretty much plays the entire show facing the amp

Your position towards the amp does play an important role; but I wonder if it's important to stay in front of the amp or maybe move away (sidewards i mean)
like:
----
amp| ----------------> me (guitar)
----

or

----
amp|
---- \
\
\
\
me (guitar)

I hope you understand what I mean :s; I could be totally wrong, but 2 weeks ago (when I was in the studio), somebody told me the position was important (but I never understand exactly what he meant; he didn't explain it all.
He suggest me to put my headstock on the monitor.. didn't work though.

But after all, I should try to lift the speakers up to my (height) because I'm playing a half stack right now. (I sit down, i get feedback more easily)




in my case it does help quite a lot!


purpose is off course to get it as quick as possble (or JUST at the moment you want). I manage to get it in like a second or something; I guess <0.5 sec is quite impossible


something i found out not long ago, does make your feedback note very clear too. I think you should mute the other strings while vibrating the wanted /other string (and note)


don't have whammy, maybe i should consider buyin a digitech



i found out that some effects do cut the signal (although quite logical) like delay
some other help to create the feedback: reverb, sustainer (distortion); problem with these lasts one is that make your sound dirty if you put too many in a chain.


Anyway, thanks a lot to the_bleeding. Seems like he's doing the same tricks i found out by experiment.
I think it's a nice trick if you use this feedback properly; i really dig the effect, sounds great and powerfull. It's quite an advanced technique imo, not a lot of people can handle this apparently (of maybe dislike feedback :P).
I hope some other people will give their views/findings about this one!

If you want feedback kinda quick do a pinch harmonic and it will go into feedback without notice, works for me. High volume is need for this too.

mm,

it's worth trying :P

Empty cabinets dont make noise...

huh ? Empty ? So you're saying the most of waht you see is just decoy and for the looks of it ?

For the endorsement check.

How many of the twelve cabinets does he actually use anyway?

__________________

He uses 4. Two for his Dry Signal, two for his wet signal. IIRC Slayer cross monitors their cabinets. Meaning at least one of each guitarist's cabinets are sitting across stage so they can hear eachother pre-front of stage monitors. The other 12 on each side of the stage are dummies.

In response to the main topic of the thread. Volume, and lots of it are needed for feedback. Feedback is a signal loop caused by having the speaker output feed back into the pickup. I'm sure you know this already. The best advice I can give you on learning how to control feedback is to start off by cranking your amp and plugging directly into the amp, nothing between the guitar and amp. Once you learn how to manipulate feedback that way, start adding effects like your distortion, etc. Won't take long before you are Feedback King and your friends will bow before your awesome prowess. You should have it mastered within a day or so. It's not like learning how to sweep pick or anything.

To be honest, i'm already trying for months, but i don't master it completely.
I think we're talking about 2 (slightly) different things.
As the bleeding does, i try to get 'feedback' (?) via my strings (amp->stings->pu). I have result of this technique, just not enough as i want
The rise time (normal note>feedback note) differs too much sometimes.

The techinque you're talking about is totally different... off course worth trying...

by the way: sweep picking isn't that difficult hey?

no way!!

Last rehearsal, I've put my cabinet on a table. Off course is more easily to get as I stand more in a direct line with the speakers.
Maybe i should consider buying a 1*12'' speaker/cabinet, which i can put in front of me (or at least at desired height)?

Anyone got an idea how to resolve this question without spending to much money on new material?
I have a peavey 5150II with 16 ohm, 8 ohm or 4 ohm output. My 5150 cabinet does only have 16 ohm.
I could buy a small table (yet solid) to put my cabinet on, but I don't have a big car. A second cabinet (full stack) is out of the question as it would be too difficult to ge it "transportated".

Damn, and my back does already hurts :P
