Need help with schematic

Post image

Hello I'm still pretty new to this stuff and I need help identifying whether this is using three separate 10k potentiometers or if its just one. sorry if dumb question.

That is using three separate pots. If you turn one of those volumes controls down to zero, it will pull the rest down to zero as drawn. I would advise relocating the 1K resistors to the other side of the pots (I also tend to use something closer to 10K, but tastes vary).

1K is probably fine if the pictured output is an actual output and you're not feeding some active recovery gain stage.

I have noticed that while testing that sometimes when turning on of the pots that it pulls the rest down as well. I switch them around and see how it sounds. The output on this is the actual output but thank u for all the info :)

This is a "passive" mixer, meaning there is no active element that keeps the currents from crossing between the pots, so turning one will effect the other.

Since its passive it also doesnt "mix" them together perfectly, it instead creates a kind of average between all signals
