I have this book, along with pretty much every bass book ever published that was worth any attention at all, lol. Unfortunately, I never cracked it open once.
My current study obsession is Janek Gwizdala's instructional material. His is the only material I've gone through more than once and I own probably 4 of his books, including his latest which was released a couple weeks ago. If you want to move out of the strictly major scale, diatonic approach to playing, I recommend his material. It's probably intermediate to advanced level, if that matters.
@Spin Doctor You’ve got some good company in me then! I’ve been meaning to list some of the books I own for sale here but haven’t yet out of fear of how long it’d take me to type it all out. Maybe I should take the photo is worth a thousand words approach....or start a library or something....
I’ve been curious about Janek’s books but find them quite intimidating for some reason. His playing is way over my head musically. One of my goals for 2021 is to make it through the Liebman book....the thump/pluck playing is going to be tough though because I’m such a novice.
