Feedback Question

Ok, so I had my first full practice for the talent show/benefit concert I'm doing in a few weeks and I had LOADS of feedback. Probably because I was 7 feet away from my amp but just in case whats in good/easy way to lower the feedback from my amp without really lowering the volume or power.

Thank you in advance

:D
 
Re: Feedback Question

if you actually need that much gain, perhaps a noise gate of some sort should be in your immediate future.
 
Re: Feedback Question

That really highpitch stuff that sounds cool at the end of a song but just times it by...10? How it be a gain issue? or just volume
 
Re: Feedback Question

Any room or stage will have spots where your guitar feeds back more than other spots. Find the spots where it feeds back less, and then you're in business.

Are you really sure you need THAT much gain, though? I for one know that I used far too much gain back when I was 16. And I play a lot of death metal, go figure.

A noisegate often does not help, if the regular play goes into feedback. It would never close.

If you want to be brutal use a parametric EQ to dip the offending frequency.

What kind of guitar is that, anyway?
 
Re: Feedback Question

My strat, 59b and volume knob :D. Could it be that I was too close? because When I crank my amp up like how I did yestrday in my house, I would have all my cords set up(10ft-boss tu2-20ft) and I dont get feedback, plus I had more room to play. I think its mainly the distance thing.
 
Re: Feedback Question

What kind of guitar?

What amp?

How much wattage?

How much gain are you using?

These are all factors in the issue of feedback. If you are using a full hollow guitar or semi hollow, volume and gain can be an issue. You will need a long chord to get you far enough away from the amp to minimize feedback. I play a 335 a lot & when I stand right on top of my amp its a problem. Ted Nugent use to mark 3 or 4 spots where he could stand to get his guitar to feedback at any time. So it is really a matter of managing feedback but not eliminating it completely. The mechanics of of this can be caused by microphonic pickups. In essence the pickup is working like a microphone. You can test this by speaking directly into the pickup and if you can hear it coming through the amp the pickup has become microphonic. This can be eliminated by wax potting the pickups, or replacing the pickups. I doubt very much this is the cause, but it is a possibility.... check it. I would say if you have not really had much issues with feedback at home practicing, then it is probably going to be related to volume & gain. The easiest thing to do is turn down the gain, then adjust your volume. If that is unacceptable, then just go get a very long chord so you can stand far enough away from your amp. Or you can also just try to turn the amp away from you so the the speakers are pointing away from the guitar.
 
Re: Feedback Question

Try backing off on the gain and see. Maxed out gain tends to make everything very harmonic & that could be all it is. You may also find some really beautiful overtones inthe guitar if you don't rely entirely on the amp.

um I cant really test the dialed back gain as of now( in my house :/) but ill seeing how it is probably thing tuesday or something.
 
Re: Feedback Question

It is very likely to help. Full gain is NEVER a good idea, unless you are playing a fairly low gain amp. The only amp I've ever had that necessitated full gain was a Fender Roc Pro 1000, and even then I used the lower gain drive channel.

Which model are you using on the VT50?
 
Re: Feedback Question

First thing I'd do is back off the gain. If I'm feeding back in the way you're describing, where it's uncontrollable, it's probably too much gain and/or volume.

There's other things I do to control feedback though... cushioning foam underneath the pickups so the pickup doesn't rattle around is one of them. Lowering my pickup about a 16th of an inch can help.

'59bs aren't too hot as pickups go, so I'd say it's too much gain and in a hot spot (where feedback occurs especially easily).

I'm using the UK 25th? I think that's supposed a modded jcm800.

what do you mean with the cushioning foam thing?

and I cant really lower my pickup..its mounted to the wood.(long story)

My guitar uses pickups mounted to the pickguard, and I play at pretty high volume levels at close proximity to the amp in rehearsal. Sometimes this causes the pickups to sypathetically vibrate in their mountings just from the sound levels, and this gets picked up and set through the amps.

I take a little bit of cushioning foam like the kind found in equipment/mic/gun cases (you can also use a cheap sponge) and cut it up to form little foam blocks that sit under/around the pickups. This stops the pickups from rattling in their mounts and stops the feedback that results from that. It won't help if your pickups are actually microphonic, though.

Here's an example of a sponge you could use:

Re: Feedback Question

But that's not doing anything about string feedback. I'd also say that just using stronger springs should help in that case.

Assuming the OP is actually sure it's string feedback.
 
Re: Feedback Question

dude, why the hell are you using all the gain on your amp? ****! dial that **** down!

tone is in the fingers bro, not the gain knob!!
 
Re: Feedback Question

Agreed. Too much gain is a reality, and a tight band can be heavy without a ton of gain. Listen to You've Got Another Thing Coming. There's 2 rhythm guitars and a bass and the kick drum working together to lay down the heavy, but the guitars don't really have that much gain individually. It's all in the layers and how tightly everyone plays.

Even for the solos there's not a ton of gain, but what's used is very effective.
