Default Newb Passive Preamp Question

I have been reading and I was wondering to build a passive preamp is it nessesary to use coax and switch the ground, or just ground the case and switch only the signal wire, if the latter is the case only a single conductor would be needed?

Am I correct in thinking this?

I was also wondering if I had a toggle switch connecting the signal directly to the output, this would pass the signal directly with no attenuation from the pot. Is this a viable way to do the opposite of mute?

Thanks,
Lyle Gordon

Default Passive Switching

I would switch the + side; connect all - sides to ground at one point.

A mute would short the input of the amplifier. . . .

Not sure where this is going.
