Hey guys, I have an acoustic 810 and a B600H head that my parents got me as a graduation gift. Unfortunately, I had an issue with the original head just before warranty was out (after a 12mo song and dance, GC finally replaced it...) and now I have a new head. Problem is, when I plugged the darn things together, only the horn works! Zero power (or something) to the woofers. Any idea what might be wrong? Tried every dang button and knob on the head as well as different cables/cable types, to no avail, so I'm thinking it is the cab but no real clue here... Any help would be appreciated. Don't post on here often, and honestly haven't gotten to play much in the last four years. Darn school and work.
