Thanks to everyone for the replies!
Let's say i'd use a gate, drive, delay, and MAYBE some modulation, and probably not always at the same time... that would be too much?
I was thinking about going direct for sound quality and simplicity purposes, but then i realized that i'd need to monitor myself (don't have an in-ear system yet) on stage, and not all venues have monitor speakers except for the singer. And the problem is that putting a simulation of a mic'ed cab thru a real poweramp and cab will sound like sh*t, and that concerns me specially because in small venues what is sounding on stage is heard aswell as what is going on in foh.
I tought about just going into a cab and mic it, but it would be nice to have one less mic with stuff bleeding into it and one less thing to knock off while moving on stage :P
