The one book every bassist should have!

Every bassist, including me, can feel a bit aimless on our practice time. We go over stuff we already know and a lip over things we need to stay fresh on. There is a book that will help you focus your studies and keep progressing. What do you think? Your financial support means everything to me. If you would like to gain access to all of my written materials, wav. Files and bonus content please consider becoming a monthly Back Stage Pass subscriber.
