Could be a reason why it's sounding thin and weak.

Also, if the pickup is way too low on set up it won't have a good output either.
i found an old crappy hand drawn diagram of a 540p someone did and it should be wired as i changed it to. red is hot to top left, white/black series to bottom right.

this pickup has an issue. not the first time I have had a bad dimarzio.... happens more with dimz than any other brand i have used which is kind of crappy because i love dimarzios. bummer.

There's also the chance it's the switch.

Try going direct from pickup to an output jack of you have another one laying around.

A jack is like 2 bucks and may be worth a test instead of swapping a pup to find out the switch was the issue.

(Ask me how I know)

the pickup was faulty. it would not ohm right, random chaos readings in MEGA OHM, jut absolutely not right at all. i put in a FRED and everything is perfect. this is 3 bad dimarzio's i have had in the last 2 used guitars I've bought. bad luck i guess.
