Fret Buzz on PRS Silver Sky?

I recently bought a PRS Silver Sky and had it shipped from Olympia, WA to ON. (Couldn't find a black one anywhere else.) A great neck on this guitar but with lots of fret buzz up and down the neck, though not with open strings. The guitar is set up to PRS spec, which is give or take .008 relief, 2.5/32 at twelfth fret low E. The neck looks totally straight. Others who have one say there's little buzz at factory spec. I have a medium kind of touch. Perhaps, just ignore factory spec....

Would really surprise me that the bridge would be the culprit. If your neck is perfectly straight, that looks like your problem. It needs a little relief. Builder's specs are a ballpark figure, each guitar is different. Olympia WA must have high humudity and your house must be drier. Wood on some guitars move accordingly to humidity. Truss rods have to be adjusted saesonally on some of my guitars from winter house heating to summer open windows.

I never measure, I do it according to the guitar response. Here's how a friend showed me and it works great 100% of the time.

First, get the neck straight. You turn the truss rod ÂĽ turn at a time, then check relief. If the neck is too concave, turn the truss rod nut clockwise to remove excess relief. If the neck is too convex, turn the truss rod nut counter-clockwise.

Begin by tuning to your normal pitch, i.e. if you normally play in drop D, tune to drop D. Retune between each adjustment. Start by setting the bridge height for frets 16 to 22, so that the strings play buzz free at the lowest possible height.

Start with low E. Plucking normally play fret 16. Lower the bass side of the bridge until it buzzes, raise until clear. Now play it from fret 16 to fret 22. Raise slightly if needed. Check A and D and raise slightly if needed to get clean notes. Remember to retune between steps. Then do the treble side. If you bend notes up here, try a few typical bends, to make sure they don't buzz out.

When all strings play clean go to the lower frets and neck relief. Play the high E string from fret 1 to fret 15, increasing relief (loosening trussrod counter clockwise) to relieve buzz or decreasing relief (tightening trussrod clockwise) to lower the string height. So tighten, by fractional turns (1/4 of a turn), until it buzzes and back off until it doesn't. If you bend strings , do your typical bends to insure they don't buzz out. Once satisfied, check the other strings and make small adjustments as needed, loosening by the slightest amount (1/8th of a turn) to relieve buzzing.

Once you have acceptable relief, (i.e. no buzz) and easy action, set your intonation and you're done.

This is the opposite order of most setup directions. It is based on performance and not measurements; hence, I don't take any. It works because the neck is immobile between frets 16 and 22. The trussrod only affects lower frets. By setting the upper end first, you know any buzzes are coming from too little relief. This method works for most guitars, with truss rods.

Can you hear the buzzing through an amp? If not, don’t obsess about it.

I too don’t worry about measuring. I just set a guitar up so it plays as well as possible. Some can have lower action than others.
Yes, I can hear it through the amp at lower volumes. I'm accustomed to some buzz, so I guess i'll need to make other adjustments.

I find the Silver Sky is a bit buzzy at factory spec, if it doesn’t happen with open notes it is usually that you need to have a touch of relief in the neck and perhaps raise the action a bit. My rosewood SS played much better with the saddles about 1 turn above factory spec and a bit of neck relief-about 0.10 (less buzz, no fretting out) The maple one I have now is perfect from the factory, I havent changed anything. I’ve never had any buzz from the bridge, tuners, springs or anything else.

It is possible it has a high fret, and the little vintage frets do wear more quickly than I’m accustomed to, so have the frets levelled and crowned would probably be the next step

If it plays cleanly with open strings, it's not a "mechanical buzz," or sympathetic ringing of some loose part. Assuming you didn't re-string with a different gauge than factory:

1) Do your measurements again, but with a capo in 1.
2) Bring it up to 2.5/32" with the capo in place. Check for buzz, and if it's present, play all the way up the neck until you get a clean note. Wherever it plays clean...that may be a high fret.
3) If it plays cleanly after putting the capo in 1 and raising the action, but the action measures too high with the capo off...your nut is high.

Young guitars do all kinds of shifting, fret-poking, settling, etc.

Thanks, will check this out. To be clear, you're suggesting raising the saddles before adding more relief? And yes, mechanical buzz is not the issue.

Some excellent suggestions here. Just to add a bit on fret height... it would not be impossible that 1 or 2 frets are a bit high. Just one fret, especially higher up the fretboard, can really affect overall setup. Checking relative fret height (i.e., 3 at a time) using even a credit card can be useful in at least ruling out whether you have any particular frets causing problems.

coyoteblue,
I don't know your experience in guitar tuning
You may know enough to risk adjustments, but not enough to be successful. You also need the right tools.
I'm not saying this is your case, I don't know you.

I have often read similar experiences on forums. After long discussions it turned out that the member was completely wrong.
