Soundcraft Ghost group fader unity gain mod.

[Brinxter]

Hi guys, I have a Soundcraft Ghost, I´m going to mod the group faders to bypass the faders at unity gain with a switch, I´m attaching a picture of one of the group circuits, would it be enough to short between pins 1 and 3 on the fader and between the output and inverting input on the opamp? But i´m guessing the resistor between ground and the inverting input has to be opened. Is there prehaps a better way?

Thanks
Birgir

I would let a switch toggle between the fader and an internal trimmer that you set for unity gain. Less intrusive and should work witch zero issues.
