Telebass Posted September 27, 2009 Share Posted September 27, 2009 Posted originally on FDP. Over the last 18 months or so, I've noticed that I'm forever correcting excess neck relief. We're not talking a lot here, but no matter, it always returns. It never gets beyond what I'd call a slightly high action, but does always return. The truss rod adjuster is a fair way down the hole now, around 3/4 inch to the top edge of the nut, and I'm wondering if I have a fault of some sort here. We don't have any great temperature/humidity issue this side of the pond (UK); things move, but not a great deal. This particular P has a very slim front-to-back neck measurement; a little too slim, maybe? Your thoughts appreciated. Quote Link to comment Share on other sites More sharing options...

Your thoughts appreciated.[/quote] the wood slimness shouldnt really affect matters i dont think its in compression as the truss rod takes the tension my guess is that the anchorag for one end of the rod is altering... on a P iirc the truss rod is adjustable from either the head or tail...body which is yours ps my rickenbacker truss rods disappeared down the neck gradually and i think i had the same problem..the spreader bar was depressing into the neck wood...poor design i put it down to no ricks in my house now Edited September 27, 2009 by mrcrow Quote Link to comment Share on other sites More sharing options...
7string Posted September 27, 2009 Share Posted September 27, 2009 (edited) Try taking the truss rod nut off and clean the threads and the nut itself. Put a smear of vaseline in the nut and on the bearing surface. This'll make the truss rod work a little better. [b] DON'T TRY THIS IF YOUR BASS HAS A 2 WAY TRUSS ROD LIKE A FENDER BI-FLEX. You can't remove the nut and you'll put a bow in the neck trying.[/b] If that doesn't work. the truss rod could be compressing the wood at the other end of the neck. I think that's what happened to MrCrow's Ricks. This isn't a problem, but will have to be compensated for. The neck stage would be to put the neck into a backbow with the truss rod nut loose, then tighten it. This way you'll have to loosen the nut to get the neck straight.

Telebass Posted September 29, 2009 Author Share Posted September 29, 2009 OK, truss rod nut off (heastock end). Nut was covered in plaster-like material, which I rubbed off. Lubricated nut threads. All went back together well, and there's no doubt that the rod works more easily now. It just remains to be seen if it's more stable than it was.

Telebass Posted September 30, 2009 Author Share Posted September 30, 2009 After 24 hours, relief seems stable at around 0.5mm. Will leave it alone tomorrow, then hit it at one of the two gigs this weekend. That'll tell me what's going on! Quote Link to comment Share on other sites More sharing options...
7string Posted October 1, 2009 Share Posted October 1, 2009 Let's hope it stands up in the heat of the gig. Keep us all posted. Quote Link to comment Share on other sites More sharing options...
Telebass Posted November 2, 2009 Author Share Posted November 2, 2009 Well, it didn't stabilise. Now I've added a spacer, clamped it into a backbow, then tightened the rod. Now I just wait and see... Quote Link to comment Share on other sites More sharing options...
