Ok, so I've tried to figure out how to take the stupid thing apart myself. With little luck I have managed to find the battery compartment. =] Thus giving me access to the pickup. =D It's a simple one knob[volume] pickup from the early ages in life.

Anyway, it's got a nut[and washer] under the knob. Like so[if this turns out right]:

------bottom of knob

unfortunately it's stuck under the knob. My only option is to break the knob. But A: how? and B: can I replace it even?

This thing has caused me to stay up till 1am this morning. If you need pictures simply ask for them. If you know exactly what to do; PLEASE HELP!

Objective: take pickup out to see what's wrong with it after changing battery.
I got some good guitars, yo.
