Variable Line Out Box ?

I ran a search and I know this has been talked about in various ways but a lot of the links are dead..

Could anyone layout how to make a ‘Variable Line Out Box with a Ground Lift switch’ for various tube amps up to 100watts to route to a WET Rig? I don’t need any cab simulation..

Thru Speaker Jacks
Potentiometer
Line Out Jack
Ground Lift Switch?

I do understand they are NOT Load boxes and must have speakers connected.


I just don’t know about values..
I see some people mention output impedance of the Line Out making them really low (under 1K) and some say 10K.. ?


I’m just looking for variable level control, transparent line out, and a possible ground lift incase needed.


Thanks for any help

Dead simple to make up.
Wattage and Z match are not important, you just need a divider.
I've built several of these and works well.
It works out about 20/1 division. If 25 k pot is not enough just use 50k.
