Ringing from my guitar

[Keenan Borgerson]

I own an Epiphone les Paul junior with a semymour Duncan sh4-jb humbucker in it and a Marshall Code 50 amp. I’m trying to find a good avenged sevenfold tone for the amp and when I try the one on the Marshall Code patches page (preset/patch is called critical acclaim) and whenever I stop strumming or palm muting the strings and leave them open, the amp squeals. I know that it has something to do with the distortion effect I put on the amp. When I have the distortion turned up a lot, there is a lot of that squealing sound I talked about earlier. The settings are:
-bass:5, gain:8, mid:7.5, treble:6, vol:9.1
-ampd silver jubilee (gate:2.5),power amp: classic Marshall 100w(presence:8.5,resonance:5), cab:1960HW
-prefx: distortion(mode:dis, drive:1.5, tone:8, level:2.7)
If anyone has any advice on what I should do, please tell me.
And yes I know this is a very long forum

It sounds like you are having feedback problems. It can either be caused by the pickups being to close to the amp or that your gain is too high. You could try to change these two things to see whether it gets better

I’ll try adjusting these two things and see if it helps. Thanks!

Like 10 minutes after i wrote this post i figured out that I just had to increase the gate/threshold on the amp and just forgot to post it.

Try a noise gate pedal. I have one and to me it works

Seems like feedback problems, try bringing down the gain or the volume, if thats helps you may need a noise reduction pedal or a noise gate whatever you like most.
