The Fender Rumble 500 was my choice. Got it last year. Before that I had a 500 watt head into a 8 ohm cab. Never needed more than the master half way open. Now I have 350 watts with the combo alone and the full 500 if I attach my old 15 inch cab to it. I've played many gigs and 250 watts was more than enough to fill all the rooms I've been in. I have a bigger rig now because it was lacking on one outdoor gig. An extension cab would have solved that though.
