Guitar pickup as analog sensor?

Arduino noob here, with a possibly dumb question: I wish to use a guitar pickup as analog sensor on midi controller, (midi in & out, 3 pick-ups for 18 strings, a 'stepped' pot for 'tuning' another for 'glide', 4 push-buttons for chords (1, 4, 5, & 6 minor) and two pots for tone and volume) any ideas?

Thank you,
