The Blackbirds, both Epiphone & Gibson, normally have only an on/off switch, that both pickups are wired to, then to the output jack.
Mine has had that switch replaced with a volume pot, otherwise the wiring should be the same.
I'll have a look when I get home, or tomorrow, and see what's going on with mine, but I've not yet been able to find diagrams or pics to compare with an unmodified one.
Work keeps getting in the way![]()
Not an awesome pic, but the best I've got, atm.
Looks like standard parallel wiring to me, just on a single volume pot.
(red & black are the pickups, gray goes to output jack)
Apparently, my google-fu is weak, I've not been able to find any pics of the on/off switch only wiring that the Blackbirds originally came with


. Mine still looks as good as that but .........
