Michael, have you reached the vibrato part of my ebook? Regardless, vibrato is a personal and subjective kind of thing. Some people like it heavy and some don’t. But if you’re cutting it off you’re obviously too heavy on it. and need to experiment a bit more. Listen to how it sounds from others and try to emmulate…I think that’s the best way to zero in on what to strive for….for the technical side of it reed the lesson in the ebook.
