Fretboard Formula Review
Fretboard Formula is an highly anticipated bass guitar course created by the developers of the very popular Bass Guitar Secrets course. It is due to be released sometime during September (2008).
All we can say at this point, is that the bass guitar course will have a lot more multimedia elements than the BGS course, and will include DVD-based training. We will try to have a review up as soon as Fretboard Formula goes live!
