I picked up 'The Jazz Bass Compendium' and found a couple of interesting practice techniques. One was what the author calls 'digital patterns.'
Basically it's aim is to help construct walking bass lines (although I think it would work for any style) by playing chordal/scalar tones over the changes of a tune using numbers instead of note names.
i.e. root = 1, dominant = 5, etc.
Anybody use this technique to learn improvisation or teach it? Anybody ever use the book?
