A preamp amplifies the signal before it goes in to the real amp, But what does this do with the tone?
What is it good for except for amplifying the signal?
A preamps doesnt amplify the sound(at least not much), its gives the sounds its shape. You get your equalisation and gain from the pre-amp.So you basically get all your tone from the pre-amp.
The signal from your pre-amp goes into your power-amp, this will amplify the signal so you can hear it thru the speakers. The power-amp is were you get your volume, and sometimes also presence.
Fx-loops are right in the middle of the pre and power-amp, so you get your fx behind your distortion, like you would do when you use alot of pedals, and no amp-distortion.
so you would have : guitar => pre-amp => fx-loop => power-amp => speaker
