Changed the strings. Unfortunately no difference.
I ll leave it rest for tonight, maybe once everything settles there'll be some improvement.

I thank you all for your confidence in me.

I did respond via PM, stating I suspect it is a defective string.

As the guitar and all its components have been adjusted in all different directions yet the problem still persists, I'm inclined to rule out any structural problems and certainly, electronic ones. The bottom line here is, if a string replacement doesn't solve the problem, the guitar should be brought to a COMPETENT tech who would be able to do a "hands on" evaluation to find the cause.

FWIW, I haven't ruled out an amplifier malady which surfaces with the high gain.

I sure wish you lived close by me Martian as techs like you are far and few between my friend!!

Thanks guys, specially Martian for your PM too.

Unfortunately I sent it before I replaced the strings and as you have already read it didn't make a difference.

About the amp comment, I forgot to mention that the problem persisted with 3 different amps and all my distortion pedals.
I have arranged to take the guitar for inspection on Thursday although the tech told me on the phone that I have already tried all possible solutions.
However, you give me hope that it is something fixable which is very valuable at this point as I was starting to admit defeat.

I will post if there is any breakthrough.
In the meantime please please share if you have any more ideas.

Again, thank you all!

Thank you so much, I'd be honored to work on your guitars!

You're quite welcome.

Like I implied above, we can only suggest without an outright, hands-on examination of the guitar.

Another thing that comes to mind though is the truss rod. Oftentimes, especially with the bi-flex ones, I've heard weird sympathetic vibrations coming from them where a miniscule tweak of the rod kills these 'alien' undertones.

So, You have tried 3 different amps? You used all of your FX with each amp?
Process of elimination now goes to an FX pedal or a cable.

I didn't Lose my mind, I traded it for this guitar.

One suggestion, it could be that the pickups are a bit too close to the strings causing magnetic resonance (string pull). Does this happen on every pickup selection or only on certain ones?

Thanks guys.

I tried all my pedals through all 3 amps.
I need to admit that through my tutor's amp the overall sound was better maybe 'cause he uses better cables indeed.
The warble was still there of course..
The pedals were also tested with an YJM Strat and an American Series with CS Fat 50s in the past. Both guitars played great which is strange as I think PUs in both these guitars are vintage speced..

My PUs are all set all the way down to the pickguard apart from the bridge which can only be lowered up to a certain point.
Could the hotter bridge PU cause the oscillation?

I know I should invest in good cables but at the moment I am saving for the guitar tech visit tomorrow.

Until then I ' ll keep trying anything that comes to mind.
Thanks again

Hi again!
So, I am taking the guitar to the local tech tomorrow and I thought I should do some more reading 'cause he told me on the phone that I've already tried everything he would have and I might need to give him a few more ideas to try on my guitar.

I would be most grateful if you validated or discarded my hypotheses.

So,
1. I realised today that the warble is not that sensitive to the neck PU height.
Then, I also know that the bridge PU is the hot wired version.
wouldn't a hotter bridge PU have a stronger magnetic influence? also, the bridge PU is the only one I cannot get as low to the plate as I would like (something wrong with the screws and the rubbers underneath the plate).
Finally, I read one of Martian's replies to a similar problem suggesting to lower the bridge PU. So I suspect it would make a difference after all.
(Sorry if this is something that would have saved you all the posting had I thought of it earlier)

2. I read somewhere about Robert Cray and a few other pros using a thinner g string (e.g. 0.16 instead of 0.17 in a set of 10s) to tackle this issue. Is this something I could try?
I though that thicker rather than thinner strings would be the solution.
And there is the wound string which I might try if all else fails..

All the best,

Trying different gauge strings in that position is at least, a cheap fix if it works........Mike

Hi guys, I took the guitar to 2 techs who both could not fix the issue but both concluded that:

1. the oscillation is not affected by PU height
2. the oscillation goes away if I turn the tone nob to 0.

I also tried a .16 g string. No difference.

The funny thing was that both techs tried 2 cheap 60s style strats which did exactly the same. An employee at one of the stores mentioned that his AVRI 62 does something similar once he heard my guitar.
I guess I will have to live with it although I am pretty sure it can be fixed to some extent.

I am not entirely convinced that they thoroughly checked the overall set up as they thought it was OK and they didn't seem to have any ideas anyway.

Fortunately they did not charge me and one of them will phone Fender one of these days to see what he can get.

In the meantime, if the 2 facts mentioned above indicate anything I would appreciate posting your suggestions.

Thanks again for all the support and advise

All the best,

3rd tech looked at the guitar today and didn't know what to do.

He then picked up his strat with vintage bare knuckle PUs i think and noticed the same oscillation.
Then I went to the store, tried the most expensive CS vintage strat and it did the same.
So I guess it's probably there if you want to listen to it.

BUT!!!!!!
I put a wound g and which solved the problem so I guess what is said about staggered pole pieces and wound 3rds is true.
The sound is different though;
not worst or better.
It lacks the overpowering tone of the g which is part of the strat legacy as I understand now.
To be honest, the guitar now sounds like a finer instrument but not so much like a "strat" in the sense strats remind of SRV or Jimi Hendrix.
I would never imagine that a faulty g string would be part of such a huge legacy..
Cleans are interestingly nice though.
There's a more woody - jazzy flavour.
And all strings together sound a bit more balanced and consistent.

However, I am determined to find and ask famous guitarists' techs on how the get 'round this as I am convinced it can be fixed or hidden to some extent and in ways other than doing vibrato or using a Suhr guitar.
Also, I heard that the ghs progressives are a bit better designed and a bit less responsive to magnetic interference.

I thank you all again, your advise has been most valuable and taught me a lot of stuff.
When I manage to eliminate the warble with a plain 3rd I will post again (under a new thread to draw attention ).

My kindest regards to all.
All the best,
