Marshall JMP Screeches

Post by Jerry2013 »

My JMP Marshall 2203 screeches/ squeals bad and hurts my ears when i turn the volume up real loud and get the guitar very close. Is this normal? I thought it might be the cheap tubes I have to use in it.

Shouldn't this go in the Marshall section?

Sounds like a guitar problem, not an amp problem. Do you have potted pickups?

Yes they are potted. Oh, can this be moved, it might belong there in the Marshall Forum.
