Post subject:  4001 truss rod adjustment

Like an idiot I took the strings off my 4001 bass and didn't get around to restringing it for several months. Now this bass that played absolutely perfect, and I didn't change the gauge of string used, has a major buzz on the F# on the E string. I believe a truss rod adjustment is necessary. Any information as to how to try and accomplish this feat!

Pull the neck into the position you want it and then tighten the truss rods or loosen. DO NOT try and adjust the rods without helping the neck, you will end up with a severe problem.
There have been loads of threads on this particular technique. I suggest you check 'em out. Some have step by step instructions. If you don't feel confident doing it, take it to a luthier who has Rick experience...

here is some truss rod adjustment info from the Ricresouce.com web page ...

It is important to note that for models made before 1984 that the truss rods were not designed to move the neck by tightening alone. For pre 1984 instruments, the neck should be moved into place manually and then the rods tightened to hold the neck in position. Failing to follow this procedure may pop the fretboard from the neck of your Rickenbacker.


Back off both nuts, then retighten just until you feel contact with the bearing plate. Tune to pitch. You need to flex the neck back towards straightness before tightening the rods. This can be done using simple gravity and (very little) muscle, or with a clamping setup.

The quick and dirty way is to put the neck across your lap. Hold down the first few frets with your left hand. Let the body hang in space. The body's weight will straighten the neck somewhat while you tighten the rods with your right hand.

The more accurate, but more slow and cumbersome way: You need two pieces of wood slim enough to sit on the fingerboard between your D + A strings. Pad the sides that will touch the fingerboard with cork. You need a reasonably stiff board as long as the neck. Last, you need one clamp with padded jaws that opens to at least 9-10". Place one small piece between the nut and first fret, the other around the 15th fret. Rest the long board on edge on these two pieces. Place your clamp at the 6th fret. Apply just enough clamp tension so that the whole affair will not fall apart. Get your straightedge. Tighten the clamp until you're satisfied (I never go for a totally straight neck). Snug up the rods. Release the clamp, and check your progress.

Howdy,

One correction to this...The newer style trussrods started in late 1984 (I believe Sept or Oct). The 1984 models prrior to this time also have the older rods which need to be adjusted in the above manner.
