I've have been getting some nasty feedback type stuff out of my amp lately. This rly, only happens when i turn up pretty loud. Not all the way, but maybe like above half. When im playing my guitar, it sounds fine. But when im not playing, i get this really loud high pitched screeching noise. It happens no matter where i stand (in front, behind, side of amp). i have a distortion pedal plugged in with a boss noise suppressor. It maybe be the distortion, but idk why. Could you guys help tell me why its doing this, and/or how i can fix it? Thanks!

unplugged your distortion pedal. i have a metal muff and im running it into a rack suppressor and it still hisses and gives too much feedback so i don't use it much anymore.

I tried it unplugged, and i dont get that high pitched squeeling. I pretty sure that it is the distortion pedal. I mean, i do get hiss and stuff with it, but i deal with that, its not too bad, but i need to know how to stop this squeeling at a high volume....

You should check if your settings are correct on all your pedals. Also, plug out the distortion pedal and see if it still has that same hissing sound. If it does, try and alter your distortion pedals settings or look into other noise suppressor pedals, such as the ISP Decimator. My Boss Noise Supressor doesnt do much for me, so I can see why it might not work for you.

When you have an amp turned up pretty loud with ANY distortion its gonna get some kind of feedback.
Try turning your guitars volume all the way down and then stand farther away from the amp facing away from it and turn the guitars volume back up and see if you still get the same results.
The guitars volume knob is your best friend.

Try an ISP decimator G string (or rack pro G if your into rack gear, and don't have a problem dropping $400) The Boss suppressor isn't going to do the job. The ISP G string gates the front of the amp AND the effects loop...based on the guitar, NOT the amp...you don't need to adjust for varying gain or volume settings, and gates MUCH faster than any other gate I have used.

Also, you could try this. Turn DOWN the trebble, and see if you can adjust the tone back where you want it with the pedal (might need to turn down the bass and or mids to get close).
Usually works with the tube amps i have run....not sure if it will help on an SS head though.

Ok, so i took some of your advice, messed around with some stuff, consulted my dad (who was helpful actually, knew what he was talking about) and, like you said, it was the guitar's volume knob. Cuz the problem was the bridge pickup. Whenever i had the amp very loud with the bridge pickup, this happened, but not with the neck pickup. And i had the volume all the way up for the bridge pickup. So, i turned the guitar volume for that pickup down halfway, and turned up the amp's volume, and it all seems to be good! Thanks for all the help
