Notes get cutted out by strange feedback, help

Hi i just bought an Ibanez Rg 2570 and i have a serious issue, i'm not an expert on guitars so i'd like some help here. After the 14th fret on the first three strings when i play some note (especially on the 17th fret) and let it ring, the note gets cutted out by a strange feedback/noise that's horrible. I can notice that especially if i hammer on instead of picking the note. The problem is that right now the store is giving their luthier the responsability to say if there is a problem or if it's normal for guitars to act like that. If he can't find a problem i'm doomed to stay with that axe, if he finds a problem then the guitar will be sent back and i'll get a new one. Can anyone tell me what can cause this kind of problem? I'm really depressed because that axe costed me a lot (for my finances) and getting it already messed up isn't help me.
By the way, i've noticed that same kind of problem but on a lesser degree even on a strat and on another rg 2570 that they had in the store.

Thank you.

Hmm... what amp have you got? Did you have the same problem with a previous guitar?

I use Gibsons and a marshall stack. And you simply cant stand too close to the amp without getting funny noises. Feedback is a natural occurance that you have to learn to control.

I can it "phasing out" when the notes turn all mushy and zap outa tune. Try muting strings 2 to 6, and then picking the 17th fret of the first string, does it still go to mush? If it doesnt welcome to the one going battle of tone versus gain :(

Hi, my amp is an ENGL screamer 50 all tube, but the problem happened also using the amps they had in the store. Yes i had that same problem on another Ibanez that i sold before just because of that terrible issue. I have right now another spare Ibanez and the problem doesn't exist with this one.

Does it happen on clean tones too?

nope, on clean tones there's no problem but i thought that it happens because with distortion you have morer sustain and you can get more accurate picking and vibration noises

Distortion is characterised by fat, fuzzy sounds greated when ou play more than one string at once. Where on a clean channel is crystal clear, on a overdriven channel the chord or notes become distorted.
So if you bar the all the 17th frets and pick the first string then 2nd u get distortion.
You have to palm mute a string after youve play it and moved on to the next.
Sweet Child o Mine intro is crystal clear. So you wonder how thats possible considering the tone comes from an overdriven guitar! Well after each note is picked it is muted before the next note is played. All guitarists do this.

It could be a number of things. Maybe your grounding isn't solid. I know when my neighboor runs his generator it does a number on my amp. Also i pick up cellphone calls, its pretty damn annyoing, lol.

Maybe dust or dirt is in your amp, but you said it doesnt do it when playing clean. Tube amps easily scream, and they provide alot of distortion. So like Axl said, you can't stand close, or point the headstock to the amp, makes the amp mad. How close are you usually to your amp when playing? And how healthy are the tubes on it?

I had this problem a while ago, everytime i played on distorion, my amp made this "static" sound, or a ticking sound. There wasnt anything wrong with my gear, just other people in the area with their electrionic's. Its really hard to answer these type of questions with alot of advice cause i cant hear the problem...is there anyway you can record using that amp on distortion to capture the sound thats being difficult?

Does that enhance feedback? Ive always thought it was a bit of a gamble when trying to get good feedback. It seems like ou can get good or bad feedback irrespective of you position. Although you do see guitarists placing the headstock against the cab at a 90 degree angel. Is that a tried and test method like?

Feedback is caused by the sound of the speaker causing the strings to vibrate. This generates a signal from the pickups, which goes back into the amp. Since the neck is relatively thin, and it usually has a big, flat, headstock on it, that part of the guitar is quite sensitive to the sound coming from the speakers.

The kind of noise i get is like an elefant that goes berserker and i'm just hammering one note and letting it ring. It happens right away, like after 1 second even at low volumes. I have another ibanez here at home and the problem doesn't show up.

So when Im standing several metres away from the speakers, with the volume not particularly high, is that just good sustain Im getting? Because I can hold a note for about 15 seconds! I thought feedback was the pickups hearing the amp... ie you can get infinate feedback/sustain even after the string does eventually stop ringing.

That's a condition called a "microphonic" pickup. It happens when the coil wires are loose enough to move around when the pickup is vibrated by the sound from the speakers. Most pickups have some kind of 'potting' material applied to the coils to prevent this.

If you get 15 seconds' worth of good tone from a note without moving your fretting finger at all, I suspect you're using high gain. The amp is saturating, so that even a small signal is enough to make it sing. It takes quite a while for the signal to fade down to some value too small to drive the amp hard. Try the same thing while playing 'clean' - by comparison, it fades out quite quickly.

Well... your rite about hi gain yes, and I can sustain a note clearly and at a high sound quality fr over 10 seconds easy. But thats probably cos I have a really good amp n guitar.
But, if its a trebly sound, particulary if my wah it switched on, then i can just stand in an direction of distance and pick the note, it will then shreak and hold for infinity!
Actually the closer I go to the amp the harder it is too get feedback because they notes jus phase out and go to mush!

I don't know about this problem, but if it only happens at the 14th fret, maybe a fret level and polish could do the trick. Sounds like the Ibenhad factory slacking on their craftsmanship.... Probably dropped the fret finishers wages down to 50 cents an hour or something...

hmm. must'a hired 'im away from Gypson.

Man I remember when you joined this forum, seems like a matter of months ago! was it? lol your at 400 posts already!
What do you do again?

I am a professional slacker....

Just took a job as a baiter on a shrimp boat.... If I work hard enough, they said they would promote me to master baiter in no time!!! :)

No seriously, I do high end car audio. I'm the idiot responsible for sticking lots of cool stereo gear in cars that don't have the room for it, like 4-8" subs in a Porshe Boxster, 2-12" subs in a Diablo, yada yada yada.... it's a living... It supports my guitar habit...
