Sort of read, sort of skimmed. I was hooping that this book would go deeper into the history of bass guitar, but it really only touched upon it in a few asides. Understandable, really, but alas. This means I need to find a more comprehensive text.
The exercises were good, and the information was helpful. Predictably, this book was more for people looking to play the guitar than for any research purposes. Which wasn't what I was looking for. This is more my fault (and trying to be lazy) than the fault of the book.
Oh, and here's looking at you, Adam Clayton. You're awesome for helping out with this text.
