    Do a search. There are already lots of threads on this.

    But if you plan on using a power amp, you'll need a preamp with that. :D

    Preamp = volume boost + tone controls

    Some of the fancier ones have effects loops, line outs for recording, etc etc.

    It's the stuff that leaks out of your speakers when your amp gets excited...

    • amplies a signal from instrument to line level
    • makes a high impedance signal low impedance
    • offers functions like EQ etc.
    • sometimes makes a signal stereo (dual mono actually) or ready for biamping
    • offers a FX loop

    That's about it.

    JMX, I think you need two preamps, if you want it stereo processed. Left and right. I'm quite convinced that when a preamp does so, it has two preamps built-in. Otherwise, it isn't possible.

    In fact... some pedals make the signal stereo or the bass itself. Rickenbacker for instance. Then link the L signal to a channel (preamp) and the R signal to another channel (preamp), so then you've got stereo.

    Yup, is should have read "dual mono", thanks for clearing that up.
