Weird thing with my S5570Q today
Neck AirNorton pickup level was very low. Turning down the tone pot did totally cancel the volume.
Visual inspection, shaking cables and things... no change.
Unfortunately, I found that my multi meter is broken, so I used the soldering iron for testing:
1.- Disconnect the neck-pup tap (to discard a leak to ground in that section the switch). No changes.
2.- Swap the hot wire of the neck-pup with the mid-pup (to discard a false connection at the switch Neck position). Neck-pup sound OK (with the switch at position 3, of course)
3.- .... but... The mid-pup (at the Neck position) was also OK. That means that the switch Neck position is ok
4.- Rewire everything as it was. Now the level of the neck-pup is normal
Maybe there was a false connection at the switch, or some metal scrap, and it was corrected after the maneuver.
It is strange, though. I am thinking about buying a new switch, because I am going to adopt this guitar as the #1 for gigs and I don't want that to happen again.

The guy that replaced the original pickups didn't do a neat job.
