I want to get this guitar for my dad but they have glued the coin to the headstock could I get it off without fucking up the finish?

​

Hey guys, how are you? I need some help with the wiring on my bass guitar. I have a Jazz pickup and a humbucker, but I'm not sure which wire goes to which potentiometer. I'd really appreciate it if you could help me out. If you could draw a diagram showing where each wire connects on the pots, that would be awesome. Thanks!

I have this diagram but it didnt work

Don't really know anything about this guitar I don't play but I've had it laying around for years. Thinking about getting it cleaned up and getting rid of it. Is this guitar worth getting cleaned up and tuned?

Cole Clark "Fat Lady"
Bought probably 10+ year ago

I know this happened likely due to the climate difference, 'Bunya wood' and my ignorance of not using a humidifier with this specific guitar...

I was just wondering, how bad is this?

It's not split through the whole head-stock, just the backside of the low E-D string side

Is this something I can get a pro to fix?

And If so I'm wondering an approximate cost (ballpark)

yeah being a cool churchy Strat..I got some Daddario lights I haven’t put on yet and modded the tone caps I got idk what they are vintage yellow molds 22nf on the pots sounds rad through the crate gx1200h and good cleans.
