I'd get "Serious Electric Bass" (The bass player's complete guide to scales and chords)by Joel Di Bartolo. This book has absolutely no TAB, starts you off by learning all the keys in the first position before branching out and learning 2 octave scales, all the scale modes, etc.
Here's the chapter list:
1) The "Gee I Did It Myself" Guide to setting up & adjusting your bass
2) The 1st position
3) Major Scales & Chords in the 1st position
4) On to some serious shifting
5) Major scales & chords outside of the 1st position
6) Major scale modes & chords
7) Major scale modes & chords part 2: putting them all together
8) 2 octave major modes & arpeggios
9) The five position system
10) the harmonic minor scale
11) the melodic minor scale
12) symmetric scales
13) The last chapter
Each chapter is somewhere between 10 & 30 pages or so and the whole book is 271 pages long. Here's the link to the product page at
