Something I've been wondering about for a while... My acoustic bass has two input jacks on it: the usual 1/4 inch + an XLR out (see photo below) Forgive my naïvety, but... why have the XLR-jack on the bass itself/what would (or could) I use it for? ...Is it there so I can plug straight into the mixer and avoid any noise/tone coloration I would get from my amp? My GK 700RB has a Direct Out (XLR) jack and the option to bypass the amp's EQ, but I guess I'm just wondering when it I would be appropriate to use the one on the bass instead. And lastly, would I get any signal loss (or other problems) if I used both the 1/4 in. and XLR at the same time?
