hi -
i am a guitar player that has become very interested in pickups - they seem to be quite important and quite expensive and i'm curious to get a sense of what can be done with them.
i recently watched this video of someone assembling a pickup from junk materials, which got me thinking that maybe i could make my own:

at the moment, i don't have any neodymium magnets, but i do have some ferrite cores. i am wondering if wrapping a thin gauge magnetic wire around a ferrite core many times would function as a kind of pickup.
after watching a number of videos, it seems that there is a great deal of sensitivity related to the number of winds and the tightness of the winding - but what i don't understand is the relationship between a densely-wound pickup and the output result. is there more hum? better frequency response? a wider magnetic field?
finally, i'm curious about the difference between a guitar pickup and a tape head. it seems like i can play sound through a tape head and a guitar pickup will amplify it, but i can't hear actual tape when i run it across a guitar pickup. what would have to change in a guitar pickup to play back magnetic tape?
