ive noticed the little rectangular piece that seems to be on a lot of vintage fenders. Ive seen it before plenty but never really though about it. its kind of placed and inch or two away from the 20th fret of the neck and is kind of slanted, unparrellel to it. i hope someone knows what im talking about be cause i previously tried to attach a picture and the file was too big. But anyway, its only the vintage fenders and ivve noticed it before but never really though of what it is. Its on both the p and jazz basses, it looks like a pickup, but i never see it on the newer ones. Kinda sad ive been playing bass for three yeasr and i cant figure out what this is but anyway i tried a search in a couple of different places abut wasnt very successful because i had no idea what to call it. So this is probably a dumb question but what is it? if its a pickup what kind is it, and can it be put on the newer models? thanks for anything.
