How to earth tuneomatic bridge
You earth one of the posts with a thin wire back to the control cavity. If you have untwisted bare flex in the hole before you put the post in you should get a perfectly adequate earth.
Build #1, failed solid body 6 string using neck from a scrapped acoustic (45+ odd years ago as a teenager!)
Build #2, ugly parlour semi with scratch built body and ex Peavey neck
Build #3, Appalachian Dulcimer from EMS kit
Build #4, pre-owned PB ESB-4
Build #5, Lockdown Mandolin
Build #6, Sixty six body for Squier
Build #7, Mini Midi Bass
... and if the control cavity is too tricky, use the bridge pickup cavity, i.e. drill a small hole from that cavity to the (typically treble side) post hole.
Thanks for your help
