sorry, its all about effects
basically an amplifier is in two sections, pre-amp and power-amp, and you plug your guitar input goes to the pre-amp stage which has all the bells and whistle ie distortion, and effects ect and the power amp just makes it louder, the effects loop basically bipasses the preamp stage so your tone isnt coloured by the pre-amp and it i then mostly from your guitar and effects
