Think I have my grandads old jar of slot head screws somewhere.
But for added mojo I would use old hand made blacksmiths nails.
What could possibly go wrong when I make a 6 string bass using high tension flatwounds.
I have a luthier mate who makes custom specials, says he can help me out, he has a 7 string neck I can have for 300 pounds, he paid 50 pounds, for my 6 string big finger conversion. And a nut he made himself with a mitre. Something about being touch sensitive in the first position, i think that means first fret only. And not anywhere else. I already have an artec hot rail pickup. Scale length 31.1"
When I make it I want serious buyers only no test pilots or dreamers. Because when they hear it through my luthier mates big rig! A Carlsbro cobra 90w combo. They will know authority and so called heft.
(Actual comment about his big rig, from one of his ebay ads years ago)
