I understand how tech21 intended the bddi to be used, the parallel out goes to your onstage amp and the xlr to the board. But i have never utilized the parallel out before. For venues with a PA, I just use the 1/4 output to my amp (for distortion) and the xlr to the board. I've always believed that the xlr out and parallel out serve the same function, they just have different cables running to them. I'm just wondering If i'm under utilizing the pedal is all. I use the sansamp mostly as an effect for overdrive/fuzz which is why I like it going to my amp. And when I use the xlr I assume that it's sending a clean unaffected signal to the sound guy I can't have the parallel out going to my head also somehow, can I?
