hey everyone, this is my first post, and i have a slight problem. About a month ago i bought a brand new les paul custom (gibson). I have found whenever i play this guitar with high gain (through either of my amps), and the guitar volume all the way up, i get a really loud squealing noise. this does not happen with any of my other guitars. i can stop it by winding back the guitar volume to about 6, but this is a pain. My main amp is a Marshall Artist 3203 - 30 watt. I dont run any distortion pedals, i just use the amp distortion. Any help greatly appreciated.
