Hi, my father gave me a bass guitar years ago. I basically have used it as art to just hang on my wall. He has always been a massive beatles fan and his birthday is coming up. The bass needs a little work. im not too worried about refinishing or restoring how it looks. i just want it to work. the input jack, volume pot, and nut are all gone. I would like to try to keep the original pickups in the guitar, but would like to redo all the other electronics while i am fixing the volume and input. What i need help with is what kind of nut, volume tone pots, and switches to use. I also need help with how to wire it all up. Also, if its not too hard to find i would like to look at getting a new bridge and pickups down the road. Do you guys know where i could find info on any of this stuff. Thanks for all the help! I am going to attach pictures of the guitar to try and help show what i need help with.
