i have some fret buzz on my jackson so i raised the action but it didn't help.
i checked the neck relief and it seems to me that there practically isn't any...
so i guess i should adjust the truss rod. i've already read some articles about it but i want to be sure that i'm not turning it in the wrong direction, and not too much...
so can any jackson owner (mine is dk2) who has experience with adjusting this help?
i need to know if i should turn clockwise or counterclockwise to get more neck relief and how long do i have to wait between adjustements?
thanks...

if you havent adjusted a truss rod before, id suggest taking your guitar to a specialist to have it looked at. adjusting the truss rod without knowing what you're doing can end up with your guitar looking like a long bow.

^no no no....

guitar head pointing to u (pickups facing up)!

clockwise : move the center of neck up
anti : move the centre of neck down

hold fret 1 and the fret where body meets neck!
look at fret 8,9 (around middle) . there should be a small gap between the fret and the string! (0.5mm)

good luck! i did this before. easy... but remember to turn little by little (abit less than quarter a turn a time) and leave the guitar to rest one hour after adjusting ... goodluck!



i think i'm not clear...

can u just measure one more time,

fret the low E at the first fret. at the same time,
fret the low E at the 17th fret, where the neck meets the body.

with both places held, look at the middle frets. 7-8th.

if the string lays on the fretwire there, u dont have enough gap.
if the string is lifted more than a credit cards thickness up from the fretwire there, u have too much gap.

remeasure and repost.

Also* is ur bridge level? it needs to almost flush with the body of the guitar.

Fret 1 1st fret, and the 16th/17th fret where the neck meets the body, adjust the truss rod so that you achieve 0.3-0.5mm of clearance between the 8th fretwire and the string. If you have no neck relief, you should loosen your truss rod and if you have too much, you should tighten it. Loosening it will bend it more while tightening it will straighten it.

Depends on how you stand and look at your guitar. If the allen key/hex wrench's 'L' shape is pointing outwards, you should anticlockwise to loosen it, and if the allen key/hex wrench's 'L' shape is pointing towards you, you should clockwise to loosen it.

Turn it 1/8th or 1/4th and let rest for about 20-30mins minimum to let the neck bow and bend to the new adjustment. DO NOT turn it too fast or too much as it will crack the inner side of the neck.

Of course for more accurate measurement you can capo the 1st fret and use feeler gauge to measure. But pointless actually, as your eyes>feeler gauge....

no, the bridge isn't completely parallel to the body, it sinks a little, but not much.
and i checked again, with capo on 1st fret and fretting the 17th fret, there is no neck relief, you can't even put a sheet of paper under the string without lifting it...
#10
first off u need to release that bridge a little. if its sunk in at all thats going to make huge difference.

so how bout u flip the guitar over and take off the plastic cover and loosen the two screws in the trem cavity a turn or so, until the bridge is flush or even a bit lifted.

then remeasure, and if u still have no relief then repost ill tell you how to adjust the neck.

i meant that it seems like it "sinks" if you think of the part that points to the neck as the "front", the fine tuners side is a little higher.
so i guess i should tighten the springs a little. but won't it mess up my tuning?

is this the way i should turn it to loosen the truss rod?

sounds like ur bridge is fine.

ok, when u dont have enough gap u turn the nut COUNTER CLOCKWISE.
looks correct in that picture.

u want to detune the guitar a little and turn 1/8", a very small amount.

then u wait an hour retune and remeasure. if there's hardly a difference then u can give it another 1/8" turn. but then leave it until tonight to settle.

the thing is, I'm having intonation problems with my guitar too, but it seems obvious what to do:
Take it to a shop, pay for a set-up once, ask to see how they do it and then you'll know, seeing as the truss rod / guitar needs setting up about yearly, perhaps more, then it's well worth the investment.

I have too much bow in the neck, so should I turn clockwise or counter clockwise?
Out here you've gotta know where your towel is!

too much bend is Clockwise turn.

dont force the turn, dont turn more than 1/4. and follow all directions in the thread.
