Ibanez RG421HPFM Feedback Issue

Hey, I've owned the new Ibanez RG421HPFM for over a month now, but I've been having a weird feedback problem. If I crank the volume on my amp to around 3, I get feedback that I haven't got from my other guitars, its an annoying hum and a high screech feedback

Has the factory pickups: DiMarzio Air Norton and Tone Zone pickups, 3-way pickup and coil tap switch. I'm using a EVH 5150 III 50 Watt head with a Marshall 1960A and a simple pedalboard. The feedback is present whenever I'm not playing the strings, and only at high volumes. Its really annoying when jamming because I have to turn up loud to be able to hear myself over the drums, and when playing shows its annoying because during pauses all you can hear is that feedback. I'm wondering whether or not it could be because of poor wiring, or if its just the pickups? If anyone has experience with wiring, pickups (these ones in particular preferably) or eliminating feedback, any theories/suggestions would be great.
 
Usually that is caused by improper gain staging. Is it just guitar>amp? Or are there any boost pedals? What happens if you turn down the preamp gain, or change the location of the amp in the room?
 
Are you sure it's feedback and not simply that the guitar isn't shielded (or not grounded) properly?

You said you are running thru a pedalboard. Try taking the pedalboard out of the signal path temporarily to see if the problem still happens.
 
***Update*** Well I had to wind up returning the guitar to Sweetwater, was having bad issues with high action even after I paid Sweetwater to do the setup and had high pitch feedback; The feedback and noise was present whenever I was not playing the strings, it was completely unplayable because of this. :no:

Yea it is a nice guitar but unboxing revealed no whammy bar and all necessary tools and the string tree for the D & G strings was not even installed at the factory and tone pot couldn't move between 9 and 10 positions so it's getting returned.

Oh man, that sucks. You gonna get another one, or look for something else from another company?
 
Sorry, but have to ask these questions -Were'd you buy it? Are you sure it's not knockoff Ibanez with fake Dimarzio unpotted pickups?

This may sound like a crazy thought, but google the knockoff guitars and pickups coming in these days -they exist in the market all over.

And a guitar that feeds back way way too much is sometimes got knock off pickups causing it

That tone pot in that Charvel is actually a No-Load pot. Try moving it a bit harder, since there should be a detente between 9 and 10, with 10 getting the tone pot out of the circuit.

This is true. It'll click when turning from 9 to 10.

If you don't like the click, replace it with another no load tone pot. Or with a regular tone pot that you've modded. I've modded two regular pots to be no load and if I can do it, anyone can. https://www.youtube.com/watch?v=fBLp53iNCf4
Use nail polish or what I did was scrape off the contact with a small flathead screwdriver.
Volume pots cannot be no load.
