i got a marshall mg 30dfx amp kinda crappy i know,anyways can anybody explain the contour nob is that the same as a midrange thanks.
On most amps, contour is the opposite of mids. (Contour High = Mids Low.) However, the Marshall MG series has the conour using the same effect as the mids. (Contour High = Mids High) Also, I'm sorry that you've got an MG Dude, that is probably the worse amp ever made.
