Finally, it's finished. Sorry for the long hiatus, was waiting for the parts to arrive. This is the end result:
If you look closely, you can see that there is a patch of different wood around the switch. I made a terrible mistake drilling with a power drill (should've used the manual one ). And had to think of something to cover up the hole. Ended up cutting a circle from plywood with a laser machine.
It's not the only flaw on this guitar, there are some scratches, chipped off pieces and of course the blisters I wasn't able to fix.
The good news is that even though this was my first time soldering, everything worked first try. The suspense that I experienced after plugging the guitar into the amp and waiting for the tube to heat up was something else
Might post a video of me playing the guitar, even though I'm not good at guitar at all (more of a piano guy, too bad DIY'ing a piano is almost impossible ).
While the guitar is by no means perfect, I have learned quite a bit during the process and it was for the most part really enjoyable. I think that's all that matters.
