thanks for the replys guys, my problem is that I want to lower a little bit the action, but I get fret buzz on the 14-18 frets, so when I look in detail, I see that the same action at fret 12 is almost the same at fret 24 (there is no neck angle).
The solution I see here is the one "Takin a ride" did, a small shim of basswood, the problem is I dont know how to cut it in angle! to be able to raise a little the headstock side of the neck pocket.
Apart of this, I think the guitar comes with a very deep neck pocket, because the tremolo is resting very deep in the body (its leveled, but it is very deep) maybe I have 1/2 turn on the studs before It reach the bottom..
Shimming the headstock side isn't going to help you get lower action, or eliminate fret-buzz... plus; if you feel the bridge is already too low in the body shimming the headstock side of the pocket is going to cause the bridge to go even lower into the body.
If you're experiencing excessive fret buzz in the upper register it's most likely too much relief on the neck.
Go to Rich's tech site at www.ibanezrules.com
for a great tutorial on setting up the action, including adjusting the truss-rod.
If after doing a thorough setup you still feel the bridge is too low in the body, you'll want to shim the bridge
side of the pocket. This will angle the neck back a bit, so you'll have to raise the bridge to maintain the same action.
Again, if you shim the headstock
side of the pocket it will raise
the action, will not solve the upper fret buzz and you'll actually have to lower the bridge even more into the body to achieve the action that you want.
