Hello I joined recently to the site and I really like ... my question is this: how can I get those artificial harmonics on the low strings screaming in the style of zakk wilde or john petrucci? I am not exactly a beginner and I can get artificial harmonics in the high strings but not as I would like in the low strings. I have a Peavey wolfgang guitar and a mesa boogie mark V amplifier. I put the gain at most but the sound that I get does not satisfy me. Can you give me any suggestions? Thank you
