The stock pickups are pretty honky, very nice midrange there in the SE Custom Semi-Hollow Soapbar I've tried and I'd imagine it's going to sound very close to the SE One, except with less sustain and more air. I think they're pretty good, even though they're not my stuff, I'm a humbucker guy
they feel just like a singlecoil with humbucker midrange, fat and cutting. Turning down the tone pot definitely warmed up the bridge tone to give a very nice woman tone, I'd say it sounds even nicer than the neck pickup with the tone control at 10.
Have you considered about adding a tone pot? you could then leave the tone pot at around 5 to get a darker tone as a substitute for the neck pickup. It won't be quite the same, but it'll get you halfway there.
Maybe John Beef could chime in on whether the small volume pot cavity is big enough to add a tone pot
I've seen his SE One project, and I really hope PRS comes up with an awesome SE like his
If the cavity is not big enough, the OP might have to route and drill the cavity a la LP Junior :dontknow: or use a push-pull pot wired as volume control and when pulled up, as a tone control.
