[sdiy] Giga-Ohm Resistors--Where?

[Theo]

Yes I already noticed these extreme value resistors exist.
But even so other than circuits running in controlled conditions to rule out
the environment or high voltage applications,
resistors of 1G or up doesn't seem a practical thing to use.
In a synth diy context it seemed like a joke or a misprint to me.

Wonder what function they fulfill in your Neumann.
And no I don't take high-end audio designs too seriously, even from Alfred
E. ;)

Cheers,
Theo
