Jazz bass controls..help.

[Linddsyj]

Hi.... recently finished a jazz bass kit... the volume controls seem to work strangely... the bridge volume seems to work like a blend knob...volume increases as its turned off... and can’t seem to get the bridge pickup on its own..  have i messed up or is that how a jazz works?(I’m a guitar player) tks appreciate it.

Sounds like you either genuinely do have a blend knob, or you've wired it in reverse.

If it's a regular volume knob, switch the wire on the left tab to the one on the right (or vice versa) so it exactly matches the neck volume knob.

If it is a blend knob, both pickups should go to the blend knob first, and from there on to the master volume. But you would probably have noticed, because a blend knob is a lot bigger (taller) because it is essentially two potentiometers stacked on top of eachother, on one axis.

Its a cheapie Thomman kit... its all pre wired no soldering 😳... cant wire it wrongly..

Interesting! 

Do you have any pics of the guts? 

What parts did you have to connect yourself? 

[Linddsyj]

I,ll post a picture......all that has to be connected(male and female plugs) are the pickups to the vol pots...and the ground wire to the bridge......impossible to get it wrong..

Ok.. tested it...its definitely a blend knob....full on it maximises the bridge pickup and minimises the neck pu.... full off it maximises the neck pu and minimises the bridge... ?

It’s not a VBT set up is it
