I tried to find this, but couldn't - sorry. I am the proud new owner of an 85 4003. I read the on-line manual, but the truss rod nuts on my bass seem much larger than 1/4 inch. They look like cap/nuts that have a regular (lock?) nut underneath them. Any help would be appreciated.

Thanks Neill

Welcome K4ese,

Does your 4003 have the two-piece 'guard? Can you get pics of the nuts on a pic hosting site? That would help a lot!

You are seeing the "butt end" of the rods up at the headstock under the TRC--your bass will have 1/4'' nuts under the top part of the 2-piece pickguard, that, correct me if I am wrong folks, will need to undergo "manual adjustment" where you push the neck into place when you turn the rods counterclockwise.

The reason there is a TRC and the rods are exposed at all is in case they need to be uninstalled and replaced.

yep - I found them under the cover - thanks - sure glad I asked. Does this mean that I have the neck that takes the special adjustment mentioned in the on-line manual? I'm not sure I understand that exactly. My neck has a very slight bow - g side is conventional bow like I'm used to seeing - whole neck - - e side just involves first 3 or 4 frets. When I loosen the strings the neck is perfectly straight. Thanks sop much for the help.

Neill

Sounds like you just need to push the neck flat (or have a friend do it) while someone tightens the rods down. Even if it's a modern truss rod system this will still work, and by pushing the neck to the desired conformation you avoid any guesswork about getting rid of that little amount of torque. This method was applied to one of my modern Rics for a mild torque and it got rid of it.
