rg3120 sustain problem

[K7]

i have a problem with a lack of sustain on the g string. it only occurs when i fret it on the 4th fret or higher. i tried to lower the pickups and it did help a little bit, but i think that when the pickups are to high all strings should have less sustain!? do you have any ideas what could be the problem or could it just be because of a bad string? i also have heard about dead spots on the neck, but i don't know what this means exactly. please tell me what's wrong with the guitar! thanks!

Sounds like it needs a setup. http://jemsite.com/tech/index.htm for more info.

Set ups are all about creating a balance of the moving parts on the instrument.The limitations are built into every instrument.The first thing I do usually is set the neck relief.This can be measured with feeler gauges but I always measure it with my eyes and hands and ears.

If your neck relief is already proper, then it is a matter of bridge height.Try raising the treble side of the bridge slightly.Bear in mind though that the action (bridge height) is usually the last thing you want to do.

I disagree. First, I set the bridge height so the action in the high frets is good, and then adjust the action of the lower frets via truss rod. I'm not saying Paul is wrong, just proposing another way.

Neck relief and trem angle first, after those are set then adjust the action. Action is effected by both relief and trem angle which is why those must be set first, any further tweak will require a small tweak of everything
