Which PU is 1?

[nicechuckh]

About to wire 2 pickups to a blend knob, no series/parallel switch. All the diagrams I've seen say PU 1 to the top, but is the bridge PU number 1 or the neck?

Can't help you with numbers.
My bass has a similar arrangement, and it is wired so the neck pickup is CCW and the bridge pickup is CW. Seems natural. Turn left for more top, right for more bottom...

Yea, I wanted to avoid turning the blend control towards the neck to turn up the bridge PU lol

check it with a multi meter

Makes perfect sense. Hope I'm better at music than wiring lol

Set the blend pot in the middle of its sweep. Wire up the cris-cross wires to connect the diagonally opposite lugs. One cris-cross will be the hot output of the blend, and the other cris-cross is earthed. To work out which is which, with your meter, find which cris-cross is short to the middle lugs. This is the hot output of the blend pot. The other cris-cross is of course, earth. (If it's an A/C type blend, the reading from middle to hot should be 10-15% of the pot's value instead of a short for MN pots)

Once you've worked out which cris-cross is hot and which is earth, then if you are looking at the pot with lugs towards you and shaft pointing up, the neck pickup hot wire should be connected to the gang that has the hot cris-cross to its right.

on a typical blend pot, if you wire the neck pickup to the set of lugs closest to the shaft you get the "normal" bass arrangement, where turning "up" gets you the neck and turning "down" gets you the bridge.

Thank you!
