if you look at my family pic. the third one from the left is finished with tung oil. yours is maple and not sure how yours would look. that bass i did it to was alder(i think). and was painted not stained.
the eight string i am building also has a tung oil finish on it as well. but same thing it was painted and i stripped it and tung oil finished it.
not to mention it would probably be a pain to get the stain off of your bass for a natural finish. but i am not sure. i am all for sanding and putting new pickups and preamps in my pilots. i own 10 and none of them have the same electronics in them. well except for my two advanced and my 83. but those will stay stock as long as i have them.
