I got a new jazz Bass areodyne and love it.
what are the knobs ?
One volume
and 2 tone or
3 Volume
1 overall Overall Volume
and volume for each pick-up.

How do you get a P tone a J tone and good mix of Both and anything other settings that give good tones?.

What strings would you use for this bass. Do you keep the Stock Pickups in or replace them.
2 volume 1 tone, on the aerodyne I played the pickups sounded great dont change them, as for the strings go with what ever is comfortable for you to play on.
