Marshall Amp

Ok, for those of you who know it, the marshall MG100DFX Combo, i was wondering if it would be stupid to take out that lead at the back that connects the Input section the the speaker, you know the one that is like a standard jack plug. i was wondering if i could take it out, put it into the input of an EQ pedal, and take another small lead and put that into the speaker, so that i can set the EQ to change the sound of all of the output of the head, as aposed to just the input sound. get me? Thanks
