www.bassguitarsecrets.com by Alex sampson Ive got his home study course, and I think. Its a good place to start. From beginner to advance, if you ever learn a scale, mode, chord,etc, and ask the question what do I do with this, or how to help open your mind about being creative, learning the basics on reading or even how to put things together. This book is for you It opens your mind up step by step, Its a good course, not like some of the dvds, and books out there that leave you with no clue. Check it out, but the thing is you have to stick with the program. We can be lead to the water, but they cant make us drink it, also find a mentor or teacher to help guide you. So check out the site it works for me, and it could work for you. If thats what your looking for on the site he will tell you what he's all about. Take care god bless!
