Let's see;
- Nut; both my Rick basses came with black nuts. The 4001's sporting a brass one now, but not because of the color - it just badly needed a new nut, and...

The stock nut's just a piece of plastic, anyhow; you can replace it with anything you like. A black Tusq one would be nice, IMO...
- Knobs; I thought the Rick knobs
were black; mine are, anyway. In any case, there's tons of set-screw replacement knobs to choose from. Try Allparts for a start...
- Bridge/Tailpiece; that's going to be a trick. The original black Rick parts are hard to find - and
expensive when you do find them. The originals had the bad habit of folding in half fairly often. The high heat that powder coating requires, didn't mix well with cast zinc, evidently... Rick didn't make very many to start with, and the high attrition rate's made them pretty scarce. Having the stock chrome tailpiece, and the bridge assembly, anodized might work, but I don't know how much heat is involved. You could check. Or, you could just paint them...
- Pickups; those are pretty much already black. The chrome surrounds, and the chrome bit on the neck pickup? They're "real" metal - as opposed to zinc -, so anodizing should work...
- Tuners; Rick tuners are Schaller BM-4s. They're available in chrome; nickel (I have these on my Warmoth Mini-P); gold; or black. Again, try Allparts...
I don't know if you've posted this question on the Rick Owners Club site here. If not, you might want to. Some very, very knowledgeable people there; and, a better than even chance that one or two of them have already done this... Good luck with it!
