I'm curious to know what the rest of you guys are doing for live shows. Since it is desirable to emulate the sound of a mic'ed cabinet for recording, is it also desirable for performing? Usually I just send the output from my preamp to the PA (via XLR). Obviously it sounds ok, and this is a common approach. But would it sound better to send the mic'ed cab sound to the PA instead (by actually using a mic or maybe a Bass POD)?
