A guitar preamp is basically a guitar amplifier, but without the power amplifier section that drives the speaker. A typical guitar amplifier consists of two components: the preamp and the power amp. The preamp is responsible for generating most of the characteristics of the guitar tone. The power amp receives the output signal from the preamp, then raises it's level enough to drive a speaker so the guitar becomes audible. Physically, a guitar preamp can be an independent rack-mountable unit, a digital device (such as a Line6 POD), a floor pedal, or even circuitry inside the guitar itself.
There are many places online to buy a preamp. Amazon sell a range of preamp products including ultra compact preamps. The site Preamp also stocks a wide range of preamps.

A microphone preamplifier (preamp) is a sound engineering device that prepares a microphone signal to be processed by other equipment. They're often best used in circumstances where mixing consoles or recording devices will be used, as microphone signals are often too weak to be transmitted and may come across as hissy or distorted.
