Okay, so I've been using the pod for guitar effects for some time now. I use it for all modulation, delay, verb and then go straight into my head. I don't use models live. Because of this, I have plenty of DSP left (especially on the 500x) and I want to put it to use by adding effects to my vocals.
The inputs are very straight forward, and I understand the internal signal routing aspect totally, so I know how to keep these two signals separate.
Problem is, I need an unbalanced output to go to the amp and a balanced out to go to FOH for the vocals. The unbalanced outputs automatically sum to mono so I can't use one of each without sending vocals to my amp!
I could use both unbalanced outs and use a DI for the vocals (seems like a TOTAL waste of a good DI and I'd rather use it elsewhere) OR I use both balanced and "unbalance" the signal going to the amp. I'm pretty handy with a soldering iron so I can make the cable, but I need to know whether to short the cold pin to ground or leave it open. I definitely don't want to fry anything. Can someone help me figure this out?
