Just finished my second attempt at improving the neck feel.
This time around, I was more aggressive in using CA glue to fill chips and fractures, and I managed to finish it nicely with 600 all the way to 10,000 grit wet sanding.
I’m pretty pleased with the end results. The black Floyd Rose Rail Tail also matches pretty well with the guitar so far. All that’s left is to decide whether I archive this pickguard with the original solder into storage and then install the Ultra Vintage Noiseless pickups or not.
