I have a lovely '72 4000 that I'm trying to get back to stock, or close to. I was investigating the nut, and found a strange condition.
Notice that on most Ricks, the nut butts up against the flat end of the truss rod cover, but there is clearly extra space here (taken up by a brass nut sitting on a small wooden block). What's going on?
That is a non Ric replacement nut with a shim underneath it ...
You can get a new replacement nut from Mike Parks for under $5 ... I restored my 68 this way ... it had a professionally installed brass nut I replaced it with a Ric nut ... I also put a new Ric nut on the Ric I sold to Steve Cooper ...
No, that's the thing...the nut and shim that are currently on there are thicker than a stock Rick nut...I guess what I'm asking is: Is there any reason my 4000 would have a slightly longer headstock or truss rod cover? Doesn't make much sense I know....
On my 4003, the distance from the inside of the nut to top center of the first fret is 1 54/64" as near as I can tell. How does that compare with yours?
That's a wee bit shorter than fret distance calculators figure for a 33 1/4" scale, but then again RIC may be compensating that distance slightly.
I put a new nut on my '68 4001 ... I had to do a little grinding ... but I sort of figure that will happen with any nut replacement ... there is always some grinding, filing or shimming going on to get it right ...
