    Hello,

    I'm trying to make an effect unit for an input. For the input I followed the mic tutorial and tried wiring a mono jack input to the Line In R and G input of the audio shield, but I can't hear anything, any ideas why this is?

    Should I try soldering the wires to the Mic and G input next to the headphone output?
