guitar pickup to analog pin?

Hi all

Has anyone tried attaching a magnetic pickup to an analog pin to use it as a sensor? How could this be done? i guess it needs an op amp circuit?

It's possible, than what's next, what do you need arduino to do with a signal?

i was thinking to map data to servo motion. I wanted to make some kind of vibrating surface for people to interact with and then read that vibration.
