In spite of the fact that I have been playing bass for 30 years, I still take lessons every few years to continually improve as a hobbyist, but serious, musician. However, with moving to a new state last year and unaware of who the good bass instructors are in my new area, in addition to a busy work schedule, I decided to give the online option a try and signed up for a premium membership at Joe Hubbard's site.
It is too early for me to give a proper full evaluation, as I have only been a member for a week, but what I can state is that the lessons I have received and viewed, in "The Lesson Lounge" and "The Bassment" sections, are very well explained and are a good supplement to my regular bass studies.
