it gets your pickups signal high enough to allow the amp doing its work. a lonely amp couldn't hear your guitar signal, hence the preamp. any amp (head, combo, rack-built) has a built-in preamp. it's a middle step between your guitar and your amp.
also, the preamp is pretty much the stage were your signal gets characterized. your preamp does make your guitar playing good or bad, not your amp.
in Italy we say it makes the 'pasta' of your sound.
you can choose to have a rack-built preamp, or just a pedal, or use your combo's preamp stage and then go thru another amp. there are millions ways to preamp your guitar, but it's not an optional: you MUST preamp.

that's what i know about preamp, sorry if i'm not too into tech, but i think you needed just an enlightment.

you can have preamps in your guitar (usually working on a 9V battery in Australia) in effects (stomp boxes and/or racks) and then in your amplifier itself.

A strong preamp will actually amp you sound enough to work on headphones with out an actually amplifier. I use a Yamaha DG Stomp box which works as a preamp.

i plug my guitar into it and then into the amp because it works as an effects unit as well. This preamp can work alone, meaning i can plug my guitar into it then go out to headphones and it works.

These sorts of things have there own output meaning how strong it sends the signal (from your guitar pickup). If the signal is too strong it starts to distort a little and clutter a little, too little signal and the sound is piss weak

So i guess a preamp 'pre powers you signal' helps you signal to become stronger (hence the reason why guitars with a built in preamp are called 'active pickups'.

Don't know if i helped
