Strange grounding (?) issue on Jazzmaster-project

[Wensell]

Hi fellow Seymour Duncan heads!

I've just finished a Jazzmaster with two SD pickups. A P90 Antiquity in the neck, and a Mini Humbucker Antiquity in the bridge..


Well, almost finished, I can't get proper grounding. Would be awesome if someone could point out my error(s)..

When I touch the strings, tremolo, volume pot the buzz declines significantly, but when i touch the tone pot the buzz gets louder.

What have I checked
- Multimeter peeps ok between connections
- Ohm reading gets down to 0 between almost all connection, except from the lugs on the three-way switch. From neck and bridge setting to volume pot I get a reading around 7,2. What does that tell me?
- I have re-soldered all the connections on the volume pot in one big mess. Looks nasty, but no improvement or negative impact on the sound.



Hope anyone has the time to help me!

What wattage iron are you using??

Good question.. I have to check that out. I have used the same iron on a Telecaster without any issues. Do you think it gets to hot ?

Just checked now, the iron is 30W.

I have ordered cobberfoil now.. maybe shielding the inner parts and the pick guard will help. Show, the time will!

Not an expert here, but I don't see a ground to your tone pot casing? Your wiper seems to go to ground through the cap to the volume pot, but the third lug and case aren't connected. I haven't seen this configuration of tone cap to volume ground before, but as I say, not an expert.

Oh, and +1 for copper shielding throughout cavity and on scratch plate , make sure it makes contact with the pot casings.
