Those that can, do. Those that can't, censor it.
Very decent of you to help out by sharing his pictures.
Now hopefully someone can see if anything else glaringly obviously incorrect in there.

Interesting, your 0.033uF capacitor between your tone and volume potentiometers isn’t sleeved either. . .My 408 ( Rosewood neck ) has been my #1 or 1a since I got it .
The pickups do have a different EQ , I call it "even" or "smooth" some would call it " flat " basically no hot spots to the EQ to my ears
I have never had the back plate off but here is mine , I would look at your ground on the tone pot it looks different.
the yellow cap ? is correct it on mine.
I would also contact PTC they can get you sorted.
I seem to remember not being able to measure mine at some point I will try again later.
It should sound like this ( I own the frost one )

Interesting. I have a DiMarzio Transition set in another of my guitars and that is also described as "flat" in terms of frequencies but it's a very responsive and juicy pickup, whereas my 408 is very -- here I go again -- "lifeless". No sustain, no harmonics, really terrible.My 408 ( Rosewood neck ) has been my #1 or 1a since I got it .

Mine has plenty of sustain and harmonics , I would first try a new set of strings , mine loves new strings.Interesting.

Maybe I just got a lemon, who knows? But I'd like to know more when you say you were "not being able to measure mine at some point". Can you measure the pickups now? If so, what have you done to change this?
Well, I'm sorry I go on about this, maybe there's nothing wrong with the guitar and it just isn't for me. But when I play it unplugged, it really rings and has sustain but when plugged it it just dies on me. Really weird.
Anyway, I'll take it to a luthier/tech in a few day, so any tips what could potentially be wrong are all appreciated. Many thanks to everyone who responded so far.
I've contacted PRS customer service. I haven't heard from them so far...
Well, I can tell you what it does. It kills the guitar's dynamics and tone. I see yours has one too. I'd strongly recommend removing it and replace it with a simple wire. You can always put it back if you prefer having it in but I doubt you would want that.It would be interesting to know what the Cap does ?? , why its there ??

Awesome!!! I knew something had to be wrong for 408 pickups to sound lifeless!!! Some of my favorite guitar pickups!!!Just got back from the tech and problem solved!
It was that big yellow capacitor between the switch and the volume pot. The tech took it out and soldered in a wire and - voilà - now the pickups measure 9.45k (bridge) and 8.47k (neck). And most important of all: the guitar came alive. Before it was lifeless and unresponsive and now it is juicy with lots of sustain. Will do some finetuning with the pickup heights tomorrow to get more note bloom but it already sings quite nicely.
The tech was only shaking his head when he saw that capacitor. Mind you, it was not a mod, it came like this from the factory. Whoever at PRS thought this was a good idea?
Many thanks to anyone who responded, especially to munyonm for putting up the pictures.

It certainly didn't jive for me. I don't think it was messed up but delivered like that from the factory and I bought it new from a reputable store. PRS must have realised that cap was a bad idea because it's gone on the latest updated diagram. The tech said it sucked out all the tone.It would either seem that the original PRS recipe for the guitar didn't jive for you, or that particular guitar was messed up. Either way it's great news that it came to life for you!
It's great that you have it sounding the way you want!It certainly didn't jive for me.

Anyway, very happy now with the guitar. It's like day and night.
That’s awesome! And huge props to everyone that tried to help. Good job, gang.Just got back from the tech and problem solved!

Removing that cap did not affect the balanced output. There is still the treble bleed cap on the volume pot, the .033uF tone cap and the 1.1k and 2.2k resistors for the tapped humbucker. Just like on the updated 408 wiring diagram.I am glad you were able to find a solution that worked for you.
One of the characteristics of the 408 guitars was the balanced output level from the single/split/tapped (whichever it was) and the humbucker selections. Did the removal of the component alter that at all?
