When I was coming up, if you wanted to learn bass, you bought a Hal Leonard book to get the basics, then spent the rest of your time slowing down records to pick out the parts. These days, there are a gazillion YouTube channels, most pointing you to the 14-day free trial of their bass school or learning system. Curious what experience you guys/gals have had with online curriculum. Did it help? Which schools specialize in which styles/techniques? Do you take Skype lessons from an instructor? Do you just glean what you can from the YouTube rabbit hole of bass education? Or maybe you still refresh your skills using an old school book?
