Sure sounds like fret buzz to me.  As hurghanico pointed out, a solid G string is always going to have the largest mechanical excursion and is definitely the most likely to sprout odd overtones as a result.

Short of changing the bridge setup I will raise the G string on the nut. I realize that this will have no effect on any tone I finger on the G string, but it should remove the problem at least for the unfingered G (if fret buzz is the issue). Softer playing should remove or at least reduce the effect too. Did not notice I does, but will recheck. Thanks for feedback.

 

This is starting to get into territory I don't feel competent of messing around with (e.g. truss rod or bridge and subsequent other setup adjustments). Any recommendations on a good place to get such work done in Phoenix AZ area or good document(s) to read about this topic?

for eventual truss rod adjustments there is this good video:

 

 

by the same guy there are also other interesting and well done guitar setups videos

...also I heard that sometimes the magnetic pickups too close to the strings can cause odd warbling sounds..

 

it seems that until now you didn't try also to lower them, so why don't you give it a try (especially with the bridge PU) ??

 

some people solved a very similar issue that way

 

give a look at this fender forum thread: http://www.fenderfor...c_number=744617

Hey, thanks a bunch hurghanico

Looks like I'll have a couple more things to try and will delay finding a setup shop in favor of learning a trick or 2 from the videos.

Sampled the trussrod one, and I am impressed!

Updates will have to wait a little as I won't be able to play for a few days.

Worth a try, but in my experience having pickups too close primarily affects the low-E and A string.  On my JTV-69 I need almost 1/4" clearance on the bottom strings to avoid warbling, but there's no corresponding issues on the high side.

yes, worth a try

everything is possible, you never know

I do not know if you've had a look at the external forum link at the bottom of my last reply ..

there the guy writes that he had the warbling problem with the first 3 high strings of a standard stratocaster and he finally resolved by lowering the pickups ..


hope to be so even in this case, as it would be the easiest solution

OK, had time to try a couple things. A little update for now:

  • It's not fret buzz (raise G string at nut and the gurgle is present even when I finger no note; not as bad as on high note, but still there)
  • It's not the bridge pickup height either (put it all the way down; no effect on gurgle besides my mags got quieter

That leaves the truss rod and possibly how the the piezo sits in the nut (maybe even the nut assembly itself). Need to do it little more research before I take it all apart and be confident I don't need a setup job after.

Tried the truss rod adjustment and found that I could not get it to move at all with the pressure I was daring to use.

It definitely does not feel loose, but seeing how easy the luthier in the video did this I suspect I need a pro that knows what he is doing (mine may not be working quite as intended).

 

Looked more into the nut and took both the G and B string ones apart and adjusted their height (just to see whether this does anything). Put it all back together and adjusted it to match the fretboard curve at different heights ... and it sounds just as badly as before.

 

Only thing I am suspicious of now is that the piezo on the G string is a tiny bit lower than the rest of the nut string indent. I cannot really see it but feel it going over it with my fingernail. Don't get quite the same feeling when I do the same on the working B string. Looks like i will be heading for a Line 6 service place unless someone has another thing to try.

Thanks for bearing with me.

What you are calling the "nut" is actually the "Bridge".    Truss Rod adjustment nut is not easy to turn.  You would want to loosen it to add more relief.  If you are not comfortable doing this I would recommend that you take the guitar to an experienced luthier (Get some recommendations!!!!) to have it set up.  He can find any problems with neck or frets.

I heard also of some people who solved strange body resonance problems changing strings gauge/tension..

Hi, just got my JTV69 yesterday and I've noticed that the alternative tuning wheel vibrates with certain notes, which I dont hear amplified (thankfully) but am a little annoyed. Maybe a similar thing with yours but perhaps the piezos in the bridge are picking up the vibration?

 

Worth a try?

Thanks for additional feedback.
Yes, I was a nut and I meant the individual string saddles of the bridge.
Ordered a set of strings with a wound G string (D'Addario Chromes Jazz Light) - the web is full of references to bad G string sounds especially for distorted sounds.
And I'll check the tuning wheel, althought I thought I already did in the very beginning.
