Never sell a 4001 to a non technical guy...

What Rod, Joshua and John said. IMO only, of course. The old style rods once set properly virtually never go out of adjustment.

Only when you change strings to a set with different tension.

I wouldn't want to change to the new rod style. I find the old style rods hold the neck in place better from season to season.

So true.

I, for one, did not like the old truss rod system until I liked it better...

As long as you use it properly and keep the total string tension below 160 lbs, you will never have to adjust it. Assuming you keep the same type of strings that is.

I believe that is because the old style rods react against them selves. You set them to react against a certain tension and they stay there. They have the same co-efficiency and react to temp the same. The new style rods react against wood that is far more affected from temperature and humidity.
My friend who owns a '72 4001 from new has never had to adjust his rods. If you change to a different string tension then the rods would need to be compensated,

Not even then sometimes.

The new style truss rods sit in a curved channel fly cut on something like 15 foot radius. To convert from old to new, you'd have to fill the routes with maple strips, then route the new style channel. Corresponding splints would have to be glued into the new channel, leaving room for the new rods. Rather than have the rods anchored at the body end like they are now, which can sometimes result with the rod nuts sinking into the neck in some cases, I'd have a brass block at the body end. That's a lot of work to convert a 4001 to a 4003.

Who or what forum do you recommend I use to find a good Rick tech in the Wisconsin area?

...I would rather rethread the old truss rods than rechanneling the neck for the new rods.

Heid Music up there is a Rick dealer, they should know how to work on a Rick. Or have you been there.....
