I love P90's and have had them in a few guitars I've owned here's but here's my question: I just picked up a Epi 56 LP and have to get used to the drastic difference between the neck & bridge pup. The neck is dark and fat while the bridge is very bright almost like a tele. Is this due to Les Paul body? On the up side when both pups are on in middle position I get quack that sounds like a strat in 2 or 4 position but the tone between neck & bridge is extreme.

Some P90s are hard to balance.

If you're getting quacky tones, they're probably out of phase.

Measure each pickup for DC Ohms resistance and report back.

Make sure you've got 500K pots in there.

I like 250k volumes and 500k tone pots with mine. It does keep that bridge pickup nice and snarly.

The guitar looks stock.
Peegoo I ain't got no stinkin meters to measure no stinkin resistance.
Leftee I'm guessing the 205k volume would cut some of that treble?
I have a ES339 with P90's and it just sounds sweeter and more balanced. This LP has the same pups so I'm kinda confused.

Yes. It will take some of the treble out. Personally, I like this setup.

15 years ago on a different forum we used to argue about these values.

And I agree with Peegoo. Something is wonky if the middle position sounds like that. Are you sure someone hasn’t been in the guitar?

Sometimes they come from the maker like that...miswired. It happens.

Is it a new Pro model with the better pickups? If it's an older one with Epiphone's basic pickups then they aren't great.

It's the newer model 2014 with nice pups. Maybe I went to far when I said quack in the middle position but the dramatic difference between bridge & neck does make for a more pronounced and pretty cool middle tone. Maybe I'll put a 250k volume pot on the bridge although it puts out a nice Albert King tone .
I raised the pole pieces and lowered the neck pup to get a bit for a brighter tone and did the opposite on the bridge but tone change is pretty subtle.

I usually adjust the bridge pickup (the whole pickup) pretty close to the strings. You have to stuff foam under it. More foam than currently installed. Assuming that’s how Epi bully these.

I got lucky last year and bought the Epiphone 56' Les Paul Custom, in Pelham Blue, from Sweetwater.
These were offered with Gibson P-90's, plek'd with a HSC.
I wanted a birth year guitar and a Gibson was just too far out of my budget and then they offered these on their website for a short period of time and took the chance to get it. I am super pleased with it and will keep it as an heirloom, but I have played it once at a show through my Marshall and got many compliments on the tone. It snarls and can play really clean.
They were costing near $900, but with all the upgraded components, locking tuners, Tone Pro's bridge and tail stop, CTS pots and Emerson oil caps, along with the treble bleed circuit, it was everything I wanted in a Gibson but with a much more reasonable price tag. It may be an Epiphone but I am not, in the least, disappointed! I have an Elitist Les Paul in honeyburst with most of the same upgrades, but put in the 57 Classics wired to the 50's wiring scheme, and it is better than my Gibson Standard. The poly finish doesn't detract from that guitar and feels amazingly wonderful, where as the nitro finish on my Gibson took a while for it not to feel tacky! Thanks to wiping it down with some Naptha and letting it air dry several times to finally have it settle down to a smooth and untacky feel. Both are outfitted with 57 Classics, but the Elitist still feels the best to me, neck wise.
Enjoy your new guit-fiddle and you'll get it dialed in and be none the happiest!

If the guitar sounds like this clip but maybe even more nasally in the middle position, the pickups are out of phase.

The output drop/lack of balance between neck and bridge with P90's is a common problem. Lots of boutique winders like Fralin and Lollar offer a 10-15% differential to compensate. I like a neck pickup around 8.0-8.2k which is about average for a P90, then a bridge pickup 15% hotter. Fralin likes to offer 5% underwind in the neck, 10% over in the bridge.

P90 out of phase
