Need help with pocket shim/bridge adjustment

So I have and older RG321MOL with the WII neck, really solid guitar, But ever since I got it I have this issue with it. So due to the indo craftmanship i get there will be some fret buzz, but this is a little different.

So everything is stock on the guitar, and the bridge saddles have to be adjusted ALL the way up almost to the point where the screws are coming out of the saddles just so there minimal fret buzz.

So Im thinking that I should put a shim in the neck pocket. All the info I can find on shimming the neck pocket is the opposite condition that I have where the saddles are all the way down and they shim the back (bridge side) of the pocket. Im thinking that I should shim the front (headstock) of the pocket.

Hi Nick,
Yes, a headstock side shim will probably solve your problem, but you should pull the neck off first to make sure that there isn't anything in there already that's causing the neck angle you have now.

Re: Need help with pocket shim/bridge adjustment

You could toss a shim in there and see if it solves the problem, but I think more investigation is necessary. Where's the fret buzz? Low frets? High? All of them? Have you checked the truss rod adjustment? Have you put a straight-edge to the frets, using feeler gauges to check clearances along the neck? When hardware has to be adjusted to an extreme as you describe in your guitar's setup... I don't think a simple shim will compensate that much.

Re: Need help with pocket shim/bridge adjustment

buzz is everywhere, more so on the E,A,D strings, relief is good, the low E has a tiny bit of room on the 8th/9th fret, I did go up and down the fret board with a fret rocker and there are some high frets but nothing too crazy.

Right now my action is like 2.5mm on the low E and maybe 2.0mm on the high e, and most of the saddles are maxed out all the way up. If I lower the saddles any the buzz just get worse.

All I want to do is lower the action to something in the ballpark of 1.5mm on the Low E.

I already had the neck off to see what was in there and to adjust the neck for side to side centering (the low E was really close to the edge of the fretboard in the upper frets) there was no extra paint, or shims in there.

Sounds like the neck is too flat.

What's "a tiny bit"? Measure. Should be in the .3-.5 mm area. I'm willing to bet yours will be lower than 0.3 if you measure it. If it is, you're pushing the boundaries of a "low" setup.

Again, measure. An unusually tall fret further up the board on a neck set up to be flatter could easily cause a lot of fret buzz every time you fret and pick a note below that point. It will take patience and some investigation, but if you check the notes where you hear it most commonly then find there's little to no clearance under the string with your feeler gauge, you can narrow down the offending fret position.

That's exceptionally low action for a guitar of this type. Remember, you're not working with Ibanez's highest craftsmanship. It can make a difference. Trying to eek out the lowest setup possible on a guitar of this kind might be asking a bit much. That's why I'm suggesting you break out feeler gauges and measure, adjust, and scientifically chip-away at the problems. I just don't know that 1.5-mm action is going to be achievable with a perfectly clear tone here.

It's also damn hard to give advice on this sort of thing without putting my hands on the thing. There's more you can check I haven't even mentioned yet, typing it's the hard part.
