Try running a ground from the master volume to the ground on the jack. That should ground out the strings, the pickup and the tone control to the same location.

Are you running sheilded cable? If not, are your cables twisted? You could be picking up some interferance with no sheilding.

Is this the pair of enclosed bass pickups wired in series that Gitty sells? If so, these are fairly high impedance at 7.75 K Ohms each. The impedance goes up when wired in series. I am using one of these in a build with both 500 K volume and tone pots. You might try bumping up your pots to 500 or 1000 K if you still are not getting good response.

 First off check your wiring to see if you have stray strands of wire touching this will cause a short  , and check all the earth wires and are you getting a good ground on the tailpiece ,check the jack plug as well earth to the centre , as all the pots and jack and the tailpiece are grounded together there shouldn't be a problem

I'll pull the strings off and take a good look....I was pretty sure it might be a grounding problem.

You don't have the signal/ground reversed?

also  .. don't  forget     the  fact  it may not be the guitar  ..    try    using a  different outlet  (or  other guitars  on  that one  )  ..   turn off   the air conditioner     and florescent   lights  etc  .. and  try a different cord  .

   before  you  start  taking apart the  guitar .

Sounds to me like you have inadvertently connected your bridge to hot rather than ground, otherwise touching the strings would be the same as touching the jack

Looking at the diagram, it looks like the bridge and the pickup grounds run to the back of the volume pot and then don't go anywhere from there. If that is what is really ther, a ground from the pot totthe jack should help.

If he'd done that then that pickups wouldn't work at all.
He's wired the strings to hot.

Mark you can get a multimeter and check your continuity from strings to the jack plug.

Arrg Stupid iPad. When I look at the diagrm as it first comes up, all wires from pickup and strings end at the volume pot ground. When I blow the pic up, all of a sudden the ground from the volume pot to the other ground wire shows. Sorry about that. It lloked like it was grounded to nothing.

I'm sure it's some sort of ground problem.. I thought I'd found it when I opened the box back up, as the folded over pot lead with the ground wire had pulled loose.
I tacked that down again, and....No love. Just the same as before.

I'll fiddle with it over the weekend here..... If the leads to the jack were reversed would that cause the probem?

YES!  Reversing the leads could definitely do that...

Did you read my post I did say to check the jack wiring
