    Preamps are things that allow you to tailor your stock bass sound to one that is to your liking and then send the signal to a power amp. Preamps don't have any power and are useless unless you have an amp.

    Basically a preamp is used for coloring of your sound, or in other words, sculpting of tone. As for the SansAmp, it gives a warmer tube sounds that can also give you a bit of overdrive. EQ is also something that is on most preamps (Bass, Mid, Treble, etc.) so you can fine tune your tone. Some preamps are located directly on your bass in the form of an eq.

    A seperate power amp is needed in order to play through speakers, this is common practice to have a seperate preamp and poweramp.

    Some of the more common preamps for bass are: Line 6 Bass Pod :D; Sansamp Bass Drive DI; SWR Interstellar Overdrive, and Grand Prix; Ampeg SVP-Pro; Zoom 506; along with many others.

    I hope I have been of some sort of assistance in this matter.

    agreeing with what they both said.. most amps you see in a guitar store are both a preamp and poweramp in the same box.. the swr bass 750, Ampeg SVT4, EdenWT, just to name a few.. most companies only make one, maybe 2 preamps and a slew of different preamp/poweramp combos. Those are essentially the same preamp with different poweramps built into them. WHen starting, its normally cheaper to get a bass amp w/ both things in it, but when you get to more high-end equipment, its cheaper, and gives you more options when you buy everything seperately.
