I'm interesting in getting a digital bass, meaning i want the signal coming out to be digital (1's and 0's), not an analog signal from magnetic or piezo pickups. I'm guessing this can either be done with MIDI or something like the Line6 Variax? is there such a thing other than the line6 variax? What are my options? hit me with whatever, and old/discontinued/vintage doesn't bother me, i just want to know what all is out there. thanks for the help!
