Effects switcher

[dze]

Hi there,

I don't know if this is the the name of the pedal that I would like to build, but basically I have 1 pedal and 2 stereo inputs. I would like to select either 1 of the stereo input or both to go into the pedal. If it doesn't go into the pedal, it will be sent into an output of the pedal. The inputs doesn't have to be summed, it can be be on it's own.

I looked at the AB pedals it seems like the right one that I could experiment with. But as with 2 stereo inputs, which means 4 mono inputs, what kind of switch should I look into?
