i guess this is known as being "hot" or something and the only was for me to turn my amp up is if i turn down my actual guitars volume switch almost all the way down, which really dampens the sound making my guitar just sound weak.

my guitar- Epiphone SG EX Prophecy

I feel like the squealing has something to do with the EMG's or something.. or maybe my guitar amp?

amp- peavey vypyr 30 (30 watt)

http://www.sweetwater.com/store/detail/Vypyr30/

anyone else had this annoying squealing noise that makes it almost impossible to play live? also after like every note a slight squeal occurs even if i turn down my guitar.

Feedback mate. Turn down your pre and/or post gain. Or just mute the strings when you stop playing

if it's squealing uncontrollably, there's something wrong.

I'll have to put the Classic T models on my to-try list. Shame the finish options there are Anachronism Gold, Nuclear Waste and Aged Clown, because in principle the plaintop is right up my alley.

Cables can go bad and cause feedback. If you are close to the amp that can cause the problem as can cranking up gain.

The following statement is true. The proceeding statement is false.

either too much disto, bad cables, or back up from the amp a little more, this usually happens to me with full gain and 50% volume with my Epiphone Les paul special and Randall RG75, it's AKA FEEDBACK, but it can get annoying, especially in jam sessions/Band Practice.

For lots of people that is a desired effect.
I've never heard of anyone using that as a desired effect.

There is controlled musical feedback (a la Hendrix and Clapton) that you get when you turn a tube amp up to the point of melt down and the notes decay into feedback creating essentially endless sustain.

And then there is microphonic squealing. Two completely different things.

^^^ that.


Feedback only begins to be bad when you can't control it.

So it feedbacks even when you roll your volume all the way down?

Sounds like some amp frazzling going on.

That shouldnt be happening. Have you got another amp to try? Probably worth trying another cable too.

Feedback is caused when the air from the speakers causes the strings to vibrate even more which is picked up again through the pickups and back into the amp, if it was guitar related, turning the volume down on the guitar would eliminate it.

The first thing to try would be lowering the gain.
Active pickups have a tendency to mess with amps that expect a passive signal, especially on high gain settings.

Higher-output amps may have a second, lower-gain input for this very reason.

If lowering the gain doesn't work, try a different cable.

PS. If you use a guitar with passive pickups, does it hum while you're not playing? Just curious.
Ceci n'est pas une signature.

I'm sorry, I have been mislead by another reply. I thought we were talking about feedback, but this seems different.

What i think is happening here is that the sound from the speakers is causing something in the pickup (or the whole pickup itself) to vibrate, causing the same sound but without any control that eventually cascades into a high frequency squeal. Aka, microphonic feedback.

well actually my only cable is kinda half broken and only works if its in the right position, so i may want to look into trying a new cable.. too bad i didn't save my receipt for the life time guarantee on it.

i'm not totally sure what passive pickups are.. does that mean pickups without batteries? if so, the squealing still exists on if i turn up my amp loud enough to play with drums but if i remember correctly it seemed like i didn't have as much of a problem before with my other guitar.

maybe i will try turning down the post gain a bit and getting a new cable. for now, as long as i palm mute whenever im not playing, the squealing only occurs slightly between chords and i will have to deal with that
