I've seen this thing (CD Rom w/Book) that gives instruction using your computer. You plug your bass right into your computer. You can play along, and it will analyze how well you're doing. I think it can also be used to record. It has a tuner, metronome, and several lessons. It looks cool, but I've heard nothing about it from anyone on any board, and nothing from BP mag. Please reply only if you've used it.... Mark
