2nd Build SHB-4

[McCreed]

I took some photos of the electrics in situ but I don't think they're clear enough for diagnostics.

My first thought, based on your previous control cavity photo, would be possibly a solder lug (or something else) shorting against the shielding. Sometimes it's the simplest reason for a fault like this.

And we have a winner! Just tested it outside the cavity with the old screwdriver trick and getting thumps from both pickups.
Thank you
