I had a chance to play through both outputs together last night and it was a fun experience. The amps were about 12 feet apart with me in the middle. I used a little reverb, delay, & comp on the acoustic amp and no effects on the electric amp. The sound was huge and put a big smile on my face. Having the amps so far apart is not the most practical set up for cable management but it sure sounded good. We'll see how it goes with the amps next to each other.
One other observation on this P24. It sustains forever.
