I think it looks really cool, from what I can tell in the photo you shared (viewed on my phone). Do you have better ones? I'd like to see it more closely.
Woah, hey now, I consider these photos to be works of art now.
I got off my a real quick and snapped a few more. Now, since you asked, let me tell you the reason why the headstock is painted.
I used the vice clamp method of bushing removal. The A tuner bushing was incredibly tight, and I admittedly cussed at an inanimate object at least twenty times. At some point the bushing decided to go all at an angle on me, probably a mere 5 degrees, and then it happened....a crack. The headstock paint, some wood, cracked w/a tiny chip. I put the vice method away, got my rubber mallet, a nail finishing tool, slowly and lightly tapped the sucker out in twenty seconds with little effort. The vice method worked great on the other three, but that A was ridiculously tight. The A hole....was not routed/bushed out properly, the diameter being less than the others. These new Yamaha’s have tuner issues, on the BB434 anyway. Still, it’s a great sounding and playing bass, and my dog is but ugly and I still have her so I’m not one to throw something away or send something back....which I wasn’t able to at that point anyway (the bass, not the dog). So, hence the paint, and why my dog wears a sweater.
The paint isn’t perfect. It reacted wildly to the layered neck, but it’ll do.
