#1
I bought a used Marshall MG30DFX and it came with a footswitch for Channel and Effects. The issue is, when it doesn't change into overdrive or clean when I switch it. It's plugged into the correct socket. Overdrive won't even work when it's plugged in.

This is my first electric guitar and amp, recently purchased, and my question is: Is it me or the footswitch?

probably cause it's the wrong footswitch for that amp
the MG30dfx will only use a footswitch that switches the channels, not one that does channels and effects like you have
