So I have money to spare, so I want to buy some gear for my rig. Right now, I have a Paul-Gilbert style rig (Guitar straight to pedal straight to amp). After seeing other Player's rigs, I have a question: What is the point of a pre-amp? what does it do? And is a head really necessary?

A guitar preamp brings the signal up to line level, and often times adds various effects (distortion, reverb, delay, flange, etc...)

If you have a combo amp, then it's got a built in preamp.

Pods and J-stations and stompboxes are considered preamps.

heads have a pre and a power amp. They're like a combo without the speakers.

head = preamp + poweramp
combo = preamp + poweramp + speaker

Head and Cab for $130? You don't need a head and cabinet, you need a psychological examination.

A pre-amp is basically a sound-processor.
Your standard combo amp composes basically of 3 separate parts;
- The Pre-amp
- The Power-amp
- Speaker

The pre-amp is your basic tone-controller, where you can adjust things such as treble, mids, and bass.
The power-amp is the part which amplifies your signal, making it louder by using the volume-pot (the gain is also a part of the poweramp I believe)
The speaker is what gives you the sound.

A head is a combination of a pre-amp and a power amp, while the speakers are in a separate unit known as the cabinet.

A pre-amp on its own won't do much for you except process your signal. Any effect pedal, multieffect and processor is sort of like a pre-amp if you like.

Alot of people tend to use different pre-amps and processors in a rack, such as eq's and distortion (if they're not using amp-distotion). In cases such as these, there's no need for a head, as all the signal processing is done in the separate pre-amp.
In these cases they usually have a separate rackmounted power-amp, and channel the signal into a cab, or straight to a PA/mixer/recorder.

the head is for the volume,gain, EQ and all the other knobs for your cabinet

Taking an Internet break for a while, will come on when I can.

this is right for the most part, but a typical gain knob is part of the preamp

Ok, thanks. I wasn't quite sure, so I thought it might be a part of the power-amp.
But when I think about it, it makes more sense in the pre-amp of course.
It sets the level of the low-line signal before it enters the power-amp, does it not?
