Hi. This is a newbie question, I know, but I would like to know pretty much everything about PODs. It is a preamp. Does it have build-in effects? It can simulate amplifiers - Is the sound anything close to how the original amp would sound? If so, why would I go out and by an amp, if I can get the sound of 100 amps through this little fella? If my amp has a DI output, can I plug in my bass and POD throug there instead of throug the PA? Other need-to-know information? Maybe someone has a link that pretty much explains to me exactly what a POD is... Thank you.
