Ok, I've had an answer from the PRS Technical Manager. I've left his name off here, just telling you so you don't think he's rude by not signing off
 Hi Phil Apologies for late reply – this sounds like some kind of dead spot issue, I will investigate tomorrow and reply in depth. Best regards Technical Manager Hello Nick, Thank you for your reply. Is this kind of issue usually fixable? Cheers Phil Hi Phil, In short no – every guitar will have one or more dead spot(s) it’s just a product of resonances cancelling each other out; people have had some success with fitting clamps to the headstock which add mass to either minimise the effect or shift the frequency affected. However I’m pretty sure certain notes shouldn’t be dead in any position – this is what I need to check tomorrow by going through a few Aces. I will let you know my findings and we’ll take it from there. Best regards Nick -------------------- SEE MY GMC CERTIFICATE  “Success is not obtained overnight.

Wow, I would love to take a look at that guitar.
I've never encountered anything quite like your description ... and I've played (not too mention owned) A LOT of guitars. -------------------- - Ken Lasaine

Yeah it's crazy Ken, the one that blew me away was detuning the string and the B two frets higher was still not sustaining

Yeah but he did say that a certain notes shouldn't be dead on all areas so I have that in my favour. My luthier has had dead spots before but nothing like this.

Did you buy the guitar new?

Yeah, late last year. Never noticed this issue though until I did a piece worth some long notes.

Weird.
Like Todd, I don't buy the PRS explanation. *Though w/o the tech having your inst in his hand he can't really assess anything. Guitars do not just inherently have dead spots - even cheap as shit ones. As I mentioned, besides owning dozens of instruments, I also worked in two different guitar shops. I have never experienced the issue you're describing. This post has been edited by klasaine: May 26 2016, 06:35 PM -------------------- - Ken Lasaine

Here's the file I sent him, B 16th fret G string (the worst one), followed by A 15th fret G string, and then B 12th fret harmonic followed by G 12th fret harmonic.
It's like this with practically every B, worse on unwound strings and worse above 12th fret than below. I think I did hit the G harmonic ever so slightly harder but it shouldn't make as much difference as it does surely. This was recorded after the luthier had done fret dressing, string change and a full setup as well as everything else he tried. It's not four minutes long, I rendered it and forgot to set the area to render and there was a muted backing track in the DAW  https://soundcloud.com/gmcphil-1/b-1 This post has been edited by Phil66: May 27 2016, 08:24 AM -------------------- SEE MY GMC CERTIFICATE “Success is not obtained overnight.

Is the the springs of the guitar or is there reverb on the amp? also could you share a side angle photo of your bridge, I'd like to see if its floating or not. Edit; meanwhile does your tuner accept alternate tuning? typical is 440hz, try 444 or 438 This post has been edited by Mertay: May 26 2016, 08:46 PM |

Yeah the ringing on the first note sounds like the string hitting a fret, my luthier moved that string up as high as possible, reset the intonation and it still sounded like it was hitting a fret.
My tuner can take any tuning, what do you have in mind mate?? Cheers Phil -------------------- SEE MY GMC CERTIFICATE “Success is not obtained overnight.

Instead of changing the note we can slightly tune that note higher or lower, the guitar tends to be forgiving to such small changes. Lets do this with the tuner I'm familiar with; go to this link and there download GTUNE http://www.gvst.co.uk/downloads.htm after loading it to the DAW, open the plug-in and you'll see a knob next to CALIB. Turn that to the right till you see 440 go to 444, nowtune all your strings to that setting and check if the deadspot got less noticable. If not, using the same knob adjust to 437 and tune again to see if it works. So we're only slightly de-tuning the guitar (all strings), we could increase/decrease the values I recommend but if too much then it won't sound well with the backing tracks. |

Hello folks,
OK I couldn't get Gtune to work, I opened it in the DAW but it wasn't getting the signal. I used my GT100 tuner, went from 437hz to 443hz and it actually made it worse. Here is the G string tuned down to F so I have to play the 18th fret to get B, I play 2 Bs and then two As, the As; obviously are played at the 16th fret where the B was played and died. I find this fascinating. No fx added, just into GT100 on fairly clean setting. https://soundcloud.com/gmcphil-1/b-stuff Mertay, here is a picture of the trem, it is floating but not as much as a floyd.

Wish it worked but the good thing is if it got worse then we know its not a fret but a frequency thing  The other option to test (which is actually not very hard to do at home but sure the luthier can also do it if you don't have time) is blocking the tremolo. In this video its explained how its done with wood but you can simply stack use a few coins too, idea here is to not let the tremolo vibrate to see if this can solve the problem; This post has been edited by Mertay: May 27 2016, 09:29 PM |

Very strange. -------------------- SEE MY GMC CERTIFICATE “Success is not obtained overnight.
