I'd say here is your challenge -Electric guitar manufacturers spend a tone of time mixing pickups, woods, parts etc etc to come up with a look and sound that has some defining distinction..... and when you buy a kit, often they come out great but a little on the vanilla side with regards to distinction -sort of like Peavey Guitars and Amps in 80s and 90s.
So if you buy a kit, plan on experimenting with multiple pickups, and other components to get it to that next level IMO
you legit do nothing other than glue & clamp. All the holes for tuners, bridge, etc. are all there for you. Just put it together. The hardest parts are finishing & wiring.
If you search enough you can find a video that PGK put out showing how to set the neck. It's kinda hilarious cuz that's all it is.......glue it.
Thankfully they do such a great job with the routing and matching the necks to the bodies that there is zero wiggle room once the neck tenon is in there.
I'll be finishing my second PGK build this spring. It's ready for paint. Still working on my spray skills with the spray gun and then I'll have at it.
