@monchavo, here are some (crummy) photos of the smaller powerchip and mag/piezo selector switch:

Being as it’s not clear in the photos: The red/white wires soldered to the top of the board and braided together in the sheath are the mag/piezo stereo output to the appropriate contacts on the jack, with the bare wire from the underside of the board wrapped up with them going to ground.

This is exceptionally useful. Thank you. I really appreciate it.

Just when I thought everything was going smoothly, a strange spanner has been thrown in the works.

The chap who owns the guitar did a "dry fit" of the Schaller switch. He notes that the switching mechanism on the Schaller fouls the tone pot when installed on the plate. He notes that flipping the switch around means that the flat side of the switch faces the pots and then does NOT foul the pot.

This seems to be a simple solution which would then require the wiring to the switch simply to be "inverted".... I am unclear if the switch would support this and if that would result in any other side effects. Is it just a simple matter of flipping the wiring diagram around?

Thanks again for your help.

It seems to me that swapping the pickup leads soldered to contacts 2 and 3 would reverse the throw of the switch for this purpose. Of course, the commons used for the tone pot-outs would be affected, as well.

So swap 5 and 6 too?
