Cheap noise gate

hi, i would like to know what noise gate would be the best. I like to play in distortion but my amp always make a death feedback (really hurt my ears) and then one of my friend showed me a deluxe big muff fuzz pedal and it had a noise gate on it, the feedback was gone. Unfortunately, i dont have a really big budget, only around 75-100$ So, what do you suggest?

Well actually, i had plenty of time to practice in clean. Better than clean, no amp at all lol for a pretty long time (for me)
But now i think we drift off subject a little bit
@MkWolfire

I have a BOSS NS-2 here that you can try out, see if it works for you.

Well within your budget. Send me a PM if you're interested.

The VoxVT20+ has an 8" speaker... but it does have a single 12AX7.

If you are getting squealing and feedback type noises, it can be pickup problems, where you're standing, the type and amount of gain you're using, even the guitar (a Gretsch archtop will squeal while an LP is quiet as a mouse) or a number of other things. Reducing the gain until you find the culprit is the solution. A noise-gate, once opened up (when you play) will lead you to the same problems. And once they start, the noise gate won't mask them, You need to mute the signal to get the gate to engage again.

Well actually the noise that is disturbing is only at idle when i do nothing, when i start playing the sound is not there anymore
A-HA! Do you use a compressor, or a compression effect on your amp?
One of the things that compressors do is treat any noise remaining when you stop playing as a low-level signal that desperately needs boosting. It's such a common consequence that there is an industry-wide term for when that happens: "breathing". That is, when you stop playing, the compressor brings in greatly-amplified input noise so that it sounds like a person taking a deep inhale.

One of my favorite-ever compressors was one I made for myself using the SSM2166 chip. The chip includes downward expansion and compression capabilities such that anything below a certain minimum signal level is reduced even further. The result is dead quiet compressor function when you stop playing.

So maybe your noise problem stems from too much compression?

Nope, never use compression. I put marshall jcm800 simulation, gain,treble,mid,bass all at the middle and a Ibanez TS9 tube screamer simulation
Go at 1:30min, thats the kind of noise that i get
Yeah, that's from too much gain and/or volume.

Okay, that clears it all up. As The Police once sang: Don't stand, don't stand, don't stand so close to me.

If your instrument is resonant, the gain is up high, the pickups are even a little microphonic, and you're facing in the "right" direction, it doesn't take that much volume at all to generate feedback. I can do it with a 2W battery-powered amp.

Justin is right in suggesting less gain. Remember that "gain" will often serve to act like compression, in that it can end up constricting the dynamic range. If you're at a close enough distance that the guitar or pickups can be jiggled into vibrating, you'll get feedback very easily.

Possible cures?
Verify that your pickups are potted (although many humbuckers are not, and deliberately so). One of the things I like to do is wrap the coils with Teflon plumber's tape. In many instances, it can be used to pack in the coil a little tighter so that it doesn't shake at higher sustained volumes.
Consider orienting your amp differently so that the chance of it being pointed directly at you is lessened.
Stand further back, and/or try not to face the amp when you play.
Don't sit on top of the amp like the guy in the video.

FWIW, the amount of gain in that video clip is appalling. There's no note definition.
It's called sludge, dude. Notice he's using a Dark Terror too; doesn't help with the definition. And that's not even so bad (relative to some stuff I've heard).

Given the intro riff I'm not sure sludge was what he was after, but who knows. I only listened to the first 5 seconds and the feedback bit.

I know that some people go for sludge, power to them.
Yeah - I meant sludge tone not necessarily the genre. He was also probably cranking it to get more noise/feedback (the better to school the kids who are legit making that mistake, on noise gates; we've all been there).

Wow this thread is amazing.
Also, i cant lower the gain, lemme explain, yesterday i did a show for a small group of people with my friend, my amp was in front of me, i was far away from the amp and the gain was set to maybe 2 but at this point, i cranked the volume/master and power setting to the max and it was really quiet, i cranked the gain just a bit and i got all the power of my amp. Btw, can someone explain me the difference between volume and master?
Think of your amp as two seperate amps. The pre amp and the power amp. The preamp adds most of the gain to the guitar signal and feeds it to the power amp. The power amp amplifies it for more volume.

The volume control (also known as a gain control) controls the output of the preamp. The master controls the output of the power amp.

By keeping the master volume low, and cranking the volume knob your pushing the preamp harder without the massive volume you'd get from pushing both sections together.

Hmm, very knteresting, so i put the go,ume knob lower when i put the master at max?

Volume knob*
If you don't want screaming feedback yes - and given what the amp is, you don't want the master at max.

Get a more powerful amp. It will make your life easier.
