Alrighty. So I just got my SAS NF back from the luthier with its new NOS one piece trem. First impressions: the guitar is definitely more articulate and, dare, I say, brighter. I like it. The best way that I can describe it is if you like the 2 piece PRS core trem then this one will give you more of what you already like about that PRS trem. It will give you MORE. In my opinion, its a 'must do' upgrade for a SE or CE to get those guitars up to Core level trem performance. My only gripe is that the NOS trem feels noticeably stiffer to me so I'm gonna have to part with some springs to get back to the comfort of the old PRS trem... but thats easy enough to do.
In comparison with the Wudtone, I feel like the trems serve two different purposes. Also, it should be noted that I installed them on different guitars and each trem had different block/saddle materials. Therefore the comparison is not a true one to one. However, the Wudtone's sustain (due to the shim) and loudness were stupid ridiculous; I did not notice increased sustain or loudness with the NOS but the articulation that resulted from the NOS was just as stupid ridiculous (while the Wudtone did not increase articulation to my ears).
If I needed more sustain or more tone dynamics (ie less 'sterile-ness' as non-PRS fans call it), I'd go with the Wudtone but I'd be picky about which material to get for the block and saddles. I understand that he offers brass now whereas only steel was available when I placed my order.
If I needed more note separation, more articulation, more brightness, or just a more 'solid' feeling trem AND I love the PRS tone as is, I'd go with the NOS trem. John Mann's trem stays true to PRS... to my ears, it does not drastically change the tone while improving the delivery... what it does is allow that PRS tone to shine through in a clearer more awesomer fashion.
These are just my thoughts based on my new trems and their differences.
