I went to play a show last night, plugged in my acoustic, and nothing happened. No type of signal to the pa system what so ever. I took it today to the guitar shop, and it worked perfectly. Is the a different way that a passive guitar has to be plugged in than an active. Everyone else have active pickups in their acoustics and all their equipment worked fine. Any help would greatly be appreciated.

Perhaps the signal output of the passive was too low for the PA system?

I dunno... I don't know much about that kinda stuff.
