I have been doing a lot of research into methods of making your guitar scream. And I mean screeeeeaaaaammmm!! Howeve, most of what I find is just lessons on pinch harmonics combined with bends or whammy bar tricks.
So I propose the question: What do you consider to be a scream on guitar? When have you crossed from squeal to scream?
For me it's when the sound of the guitar gets so much grit that you have to say "ooooohh" which means there are a lot of ways to scream. Just like with your voice or any other instrument.
Been a while! Good to be back
