I hate to admit it, but here goes: I hate practicing the bass, mainly because I miss the dynamics of working through the songs with a band, and I'm overwhelmed with everything there is to learn. I learn best from practicing for...a practice session and then actually working on the songs with a band.
Do you practice much? And if you do, what are you practicing? I really do want to work on my skills, mostly by expanding my knowledge of theory and applying it to my playing.
