Hello.......I have been playing bass for about 6 months. I have taught myself the whole time. I not a great player but I'm at the point where I can't get any better. I'm gettin sick of gettin tabs off the internet that are completely wrong and wastin my time with that. Do you think that it's worth buying any books or videos. If so which ones? I know the basic stuff so I don't need beginner books. I play by finger and by pick. Or is there another way that I can progress in advancing. Any reply would be greatly appreciated.
