Hi LATS.

I understand about the common ground.

What I'm wondering is whether I can pick a point in the 'harness' setup and wire it to my common ground. I'm visualising this as a straight series connection. Do you think that this would 1/ be effective and 2/ avoid ground looping?

I would ground the pickups & the bridge wire to the common as well.

I could zip and email the picture to you if you were curious.

Thanks again. Hope to have some progress to report ..er...soon.
