The first part of your post is incorrect, What video did you watch? The second part both humbles and confuses me that you would call me an expert (I'm not) but I promise I'm not evading anything. David is very clearly paraphrasing an actual conversation that took place between him and Paul. So to make it extra clear for you ill go ahead and transcribe David Grissoms words at the same time giving you not one, but two definitions, that's value!
"And Im like what is Sinker Mahogany? And he (Paul) explained to me that Sinker Mahogany is uh the blanks come from mahogany trees that have been cut down and apparently they are too close to the river or lake uh that they grow next to that they fall in the water, they go to the bottom of the river or the lake. They're there for a number of years and the process, uh, the pressure thats put on the wood underneath the water causes the sugar , the naturally occuring sugars and minerals in the wood to break down quicker than they would otherwise..."
There is a definition ^ We shall henceforth refer to it as PRShDEF#ONE, it is in line with the industry standard definition of Sinker Mahogany***(see references below)
He continues with
"You know he (Paul) also explained to me that if you take a 400 year old Stradivarius violin, that process is occuring within that guitar, the difference here is that you have a wood that is available in very limited quantities, but the process of those compounds breaking down occurs in a much quicker pace so the effect is that the wood itself is much more resonant"
He goes on to conclude this section with
DG: "So Paul says hes been trying to get a hold of this wood (the reclaimed river wood referenced as PRShDEF#ONE)for 20 years
Lets move on a bit to the video of PRSh at the factory, you know the one where he discuses "Finding a truckload of wood so heavy and dense the illusion is that it would sink in water"
Lets refer to this definition as PRShDEF#TWO
We now have two very different definitions (PRShDEF#ONE and PRShDEF#TWO) of Sinker Mahogany credited to one man. This creates confusion and quite apparently controversy among those who expect one or the other.
My original intention in posting the Grissom video was to demonstrate that Paul knew what the industry standard term for SM was (PRShDEF#ONE), so much so that he educated one of his most famous artists on its provenence All the while taking a different wood (PRShDEF#TWO) and naming it the same thing. This sounds like disingenuous marketing to me.
I dont think there was some massive conspiracy in Maryland to dupe guitar players around the world, PRS has a long history of great instruments and customer service. I just think the hype machine got a bit ahead of itself here and someone demonstrated a poor lack of judgement
I would also like to make it clear that I dont care if wood comes out of a river or the Popes back yard if it sounds good im all for it, I cant wait to try one of the SIG LTD's even with the unfortunate marketing gimmick its now attached to.
***Here are sources backing my above claim that reclaimed wood that has been submerged is referred to as 'Sinker' in the industry at large thus constituting a standard definition, let me know if you need more...
