Hallo, I need some help. I ordered Nordstrand DC5 pickups, and as I am currently broke

, will have to use them in passive mode only for some period.
So, if someone can help me, I would need some suggestions for potentiometers which would be suitable for these wiring. I am looking for vol-vol, in my opinion there is not need for a tone pot
btw, if that matters something, coils are wired in series
thanks,
Slobodan
