Played an outdoor gig last Sunday with eight bands. A couple were solo acts but most were full bands. Now for the terror factor. Turn around time was 10 minutes.

Fortunately , the stage had access from the rear so we could set our stuff on the stage earlier and the drums were backlined. Also , fortunately , the sound guy (the drummer in my band) was really on it and did an unbelievably good job. By the time we got to our set , the show was only about 10 minutes behind schedule. Amazing.
I never was so happy that a while back I down sized from the SVT Classic rig to a PF 500 and a 2 12 av.
Not sure if this really belongs in this thread as there wasn't any rentals or backlined stuff other than the drums.
