I wish that the guitar tutors would talk about string gauges a little more. Several genres of music are performed on Lick Library DVDs, and with so many instructors, each has an individual preference on their guitars and a style of music preference in string gauges. I don't necessarily mean brand names... I understand they have advertisers in the Guitar Interactive Magazine. What I mean is gauges of each individual string to achieve the genre effect or sets of strings to use.
For example, I heard something about lighter gauge strings for ballad tracks from Jamie. I haven't heard a lot about string gauges so far from other tutors. I see an advertisement on this page for strings, but I don't know a thing about guitar strings to use, other than articles I read on the Web.
Maybe someone can refer me to a specific lesson that addresses this issue of guitar string gauges.
