about the MOD, it's actually just a modification sa pedal.. generally, meron ka stock na pedal tapos may mga binabago sa internals and other components to improve, subjectively, the sound quality and/or durability..  

or if you meant MODULATION pedals.. yun yung mga extra effects to add flavor sa sound mo other than the clean tone and distorted signal..  
examples include chorus, flanger, phaser, delay, etc..
