Found a video I wish I would have seen. Sharing for the next guy. I did a bunch of searches on how to mount humbuckers before I tried myself but they all had the trim rings. So I went off on my own. Here is how to actually direct mount humbuckers.
I of course found this after I tried a 2nd time to mount them myself and ended up drilling through the back to fit the screw... I was able to fill it in and other than feeling a bump I don't think anyone else will notice, but, you know, I will. I was almost convinced I could call this my actual first build instead of a trial prototype. Such is life. Upside is now I feel totally free to mess up - in minor ways. I still want to play it
My strings came in so I filed the grooves in the nut down further while they were off and it helped the dropoff from open to 1st quite a bit. The action is still too high so I need to do some more filing.
The amazon knobs I ordered also came in and plate covers are in place. I'll get some finished pictures up soon and once I get that nut figured out, I might make a video of how it plays (warning: I'm not very good).
