caprae Posted June 30, 2006 Posted June 30, 2006 Okay, I've got this bass pulled apart and I only want to do this once. The access to the truss rod is at the body so you have to pull the neck off to get to it. It is my understanding that to straighten it - take away relief - I need to turn the screw clock wise. Is that correct. This is a 1989 ESP bass. Raise your children and spoil your grandchildren. Spoil your children and raise your grandchildren.
caprae Posted June 30, 2006 Author Posted June 30, 2006 Forget it. Its as clockwise as it gets and only turns slightly CCW. Something interesting though. NAMM '89 is written in pencil on the neck. Hummmmmm.......One guitar tech said he thought this was possibly a custom job and said it was definitely California made.....Hummmm........ Raise your children and spoil your grandchildren.

Guitarzan Posted June 30, 2006 Posted June 30, 2006 be very careful man, what you should do after the neck is off is remove the nut and clean and lube the threads. then replace the nut and try to remove the relief. http://www.soundclick.com/bands/pagemusic.cfm?bandID=193274 rock it, i will
caprae Posted July 1, 2006 Author Posted July 1, 2006 I'll have to look at it again. I should have taken a picture. It had a round piece with a cross cut out so you could fit a slotted screwdriver in either horizontally or vertically. It was really tight so I didn't feel good about messing with it. I'm wondering what the NAMM '89 meant. I'm wondering if this was built for that show. Possibly an update to the 400 series? Who knows. Raise your children and spoil your grandchildren.

Guitarzan Posted July 1, 2006 Posted July 1, 2006 alot of makers produce special guitars/basses for NAMM. i have seen Godin LGsp90's specially made for NAMM with quilt tops. you probably have a NAMM demo model. http://www.soundclick.com/bands/pagemusic.cfm?bandID=193274 rock it, i will
jimash Posted July 1, 2006 Posted July 1, 2006 Loosen it as much as possible without taking it apart ( the truss rod) drop some oil in there (very little) Let the neck relax for some days till it finds it's natural shape ( weeks sometimes) Then tighten it up good.
caprae Posted July 1, 2006 Author Posted July 1, 2006 jimash - is there a chance of it warping at all by doing this? Raise your children and spoil your grandchildren. Spoil your children and raise your grandchildren.
jimash Posted July 1, 2006 Posted July 1, 2006 Yes there is. You have to assume they built it straight to begin with. a fairly normal temp/hunidity range in your area is another factor. But I have had good luck fixing necks by letting them relax (days to weeks) for a while rather than just squeezing them more. Then when it looks good with no strings you snug it up real good before you put it back on in this case. But you do have to be able to get the thing loose to start. Jim
caprae Posted July 1, 2006 Author Posted July 1, 2006 Okay, that's starting to make sense. I'm going to have to ponder this one as I don't want to take a chance on damaging it. I wish I had taken pictures of it when it was apart so we could talk more specifically about it. Raise your children and spoil your grandchildren. Spoil your children and raise your grandchildren.
jimash Posted July 2, 2006 Posted July 2, 2006 If you let it relax off the guitar then if it's still bowed you can do the dirty.place the neck face down between two chairs . Apply pressure to the back to straighten it. With your other (possibly third) hand tighten up the rod while you have the shape you want. But I have seen lots of neck that straighten out with no tension at all for a while.
