Got the screws extracted and chiseled out a 1/8" deep pocket for the bridge. Got some nice stainless screws. Everything is back together and the bass has a proper setup now. I needed a quarter turn on the truss rod and a few other minor adjustments but my guess at intonation was dead on, which is good because the intonation screws on this bridge are hard to reach.
It's pretty much done at this point. Once my son gets back home, all we need to do is pick a spot to put my brand on it. I usually do the back of the headstock, but, well, that ain't gonna work!
I really love the head piece that came with this bridge, how it matches the shape of the end of the neck and has the little hole for the truss rod. It makes for a really clean look. I wish they made a left handed version of this head piece, I would use it in an instant on a bass for myself. The bridge itself has some quirks but I do like it and it gets the job done.
The pickups sound great. They're really clean and open, and with the tone rolled off and mid cranked up on the amp, they get a great vintage-y thump. I would definitely use these pickups again any time I wanted a true single coil.
I weighted it and was surprised at how light it was, 6 lbs 14 oz. I was surprised, it feels more substantial than that. The bridge is suuuper heavy. I weighted my 6 string for comparison, it's 9 lbs 7 oz. Goes to show you what a big solid neck can do to an instrument's weight.
Considering this thing was born from hacking up a half finished 20 year old semi-abandoned project, I am very satisfied. I can't wait to get it in my son's hands once he's home.
