Looks like a MIM P deluxe with a fake sticker (or different neck as the sticker looks pretty real) or plain ol P with an added J. There are many, including probably yourself, that know much more than me about these things. Plugged in for curiosity.
It says replica so it must be a parts bass take the neck off and check for any info?

The owner said that he changed the pots to the Polish ones (prolly a telpod ones). Two knobs came from Defil, and the pickups are probably presto too. Dont see a zero fret, so i think the neck is not a defil one. As said may be a parts bass, but I think made mostly in poland
