    Ok, I know this is a stupid question. But here it is anyway: What is a Pre-Amp?
  2. This question has been asked many times-
    You can probably do a search and find many answers, that will be better but here you go.

    A preamp is a part of the signal chain, that brings up the voltage from the bass up to a voltage, that the Power Amp can use. Also, the Preamp is where all tone shaping takes place. Most Preamps have at least a three band EQ, and a lot of times several different effects, such as chorus, and shelving. The power amp is what actually boosts the signal to a speaker, that basically makes it really loud. Usually in a combo amp, and a typical head(amplifier), the preamp and power amp are one in the same. But some people like their pieces separate, where the preamp is a separate unit from the power amp.

    Basically Preamp has a lot of controls, power amp has a volume knob:D
